Arduino IoT Cloud Variables description

The following variables are automatically generated and updated when changes are made to the Thing

float temperature;

Variables which are marked as READ/WRITE in the Cloud Thing will also have functions

which are called when their values are changed from the Dashboard.

These functions are generated with the Thing and added at the end of this sketch.

#include "thingProperties.h"

#include <OneWire.h>

#include <DallasTemperature.h>

#define ONE_WIRE_BUS 13

OneWire oneWire(ONE_WIRE_BUS);

// Connect to Arduino IoT Cloud

ArduinoCloud.begin(ArduinoIoTPreferredConnection);

The following function allows you to obtain more information

related to the state of network and IoT Cloud connection and errors

the higher number the more granular information you’ll get.

The default is 0 (only errors).

Maximum is 4

Sketch generated by the Arduino IoT Cloud Thing "Untitled"

https://create.arduino.cc/cloud/things/d96be7c3-073d-4272-836b-3f69ceedd1a6

Arduino IoT Cloud Variables description

The following variables are automatically generated and updated when changes are made to the Thing

int sm_sensor;

bool esp32_relay1;

Variables which are marked as READ/WRITE in the Cloud Thing will also have functions

which are called when their values are changed from the Dashboard.

These functions are generated with the Thing and added at the end of this sketch.

#include "thingProperties.h"

int relay1=4;

int soil_sensor=34;

void setup() {

// Initialize serial and wait for port to open:

Serial.begin(9600);

// This delay gives the chance to wait for a Serial Monitor without blocking if none is found

delay(1500);

pinMode(relay1,OUTPUT);

// Defined in thingProperties.h

initProperties();

// Connect to Arduino IoT Cloud

ArduinoCloud.begin(ArduinoIoTPreferredConnection);

The following function allows you to obtain more information

related to the state of network and IoT Cloud connection and errors

the higher number the more granular information you’ll get.

The default is 0 (only errors).

Maximum is 4

setDebugMessageLevel(2);

ArduinoCloud.printDebugInfo();

}

void loop() {

ArduinoCloud.update();

// Your code here

sm_sensor=analogRead(soil_sensor);

delay(500);

if(sm_sensor>1200)

//modify this value based on soil moisture sensor reading

{

digitalWrite(relay1,LOW);

}

else

{

digitalWrite(relay1,);

}

Since Esp32Relay1 is READ_WRITE variable, onEsp32Relay1Change() is

executed every time a new value is received from IoT Cloud.

void onEsp32Relay1Change() {

// Add your code here to act upon Esp32Relay1 change

if(esp32_relay1)

{

digitalWrite(relay1,HIGH);

}

else

{

digitalWrite(relay1,LOW);

}

Advantages and disadvantages of Arduino IoT cloud (Pros & Cons)

2022-01-12T17:57:00.006+05:30

Hi ! Everyone

This is what my reviews after using the Arduino IoT cloud if you have something different points then you can mention in comment section. I hope you will find it helpful. I am writing the summary of the projects that I have created using the Arduino IoT cloud.

These are the pros and cons of the Arduino IoT cloud Platform

Pros:

• It is Easy for beginners, fast for professionals as we can able to create things very quickly.

• Based on the Arduino environment familiar to millions of user

• You can directly program the board from Arduino web editor itself and it has all the necessary libraries to work with.

• One can Quickly build remote sensor monitoring using simple widgets

• We can connect to a spreadsheet, database, or automate alerts using webhooks

• Arduino IoT cloud platform now started supporting the third party boards that is ESP-32 and ESP-8266 (Node MCU)

Cons:

• It has very less widgets 

• There is very little space for customizing  widgets like pointer ,colour etc

• Sometimes device shows offline even it is connected to the cloud

• Here we are not able Export a Device's Data in CSV

These are the projects that I have created using the Arduino IoT cloud.

Introduction:

The Internet of Things has given rise to plenty of exciting new projects for makers. It's both interesting and practical to be able to develop remote sensors and gadgets.

Allowing IoT devices from multiple manufacturers to interact with your innovations will open up a lot of possibilities, including some you might not have considered before.

In this getting started guide of Arduino IOT cloud we will learn about how to use Arduino IOT cloud with Esp32 board.

Arduino IOT cloud

What is Arduino IOT cloud?

Arduino IoT Cloud is a web-based service that allows users to create connected devices quickly, easily, and securely. Multiple devices can be linked together and data can be exchanged in real-time. Users can also able to monitor the data using a simple user interface from anywhere. one can also use the android application for monitoring and controlling the devices.

Because Arduino IoT Cloud is completely integrated into the Arduino Create ecosystem, one can easily create a template code in Arduino IoT Cloud web-based editor and upload it to your board.

Setting up the Arduino IOT cloud account

How to set up an Arduino IOT cloud account?

A few basic steps are required to set up the Arduino IoT Cloud and explore the various capabilities available. So, let's look at how to get from point A to point B!

Creating an Arduino Account

For using Arduino IOT cloud Platform we need to sign up for the Arduino account just click the below link

https://id.arduino.cc/?iss=https%3A%2F%2Flogin.arduino.cc%2F

Go to Arduino IoT Cloud

Now you have successfully signed up for the Arduino account, you can access the Arduino IOT cloud by clicking the link https://create.arduino.cc/iot

Creating a thing

how to create a thing in Arduino IoT cloud?

Inside creating thing in Arduino IoT cloud there are 3 steps we need to complete

Adding Variable

2. Adding Device

3. Setting up the Wi-Fi credentials.

The way to the Arduino IOT cloud begins with creating a new thing. in this section need to select the device that we are going to use, in our case we are using 3rd party device that is Esp32 board.

Next, we will select the Wi-Fi network to which our board is going to connect, after this, we need to create variables to store the temperature and humidity so that we can monitor the sensor data over the dashboard.

This is the area where whatever changes that we have made are automatically generated into the Arduino Sketch file.

Let's follow the picture step to add a Variable.

This is where you'll make changes to the parameters of the variables.

Begin by naming the variable in the same way that you would any other variable in Arduino programming. Here I am declaring the variable name temperature for storing the temperature value.

After that, we can choose a variable type. There are several types to pick from, including several "special" types you've probably never seen before.

After that, we can choose a variable type. There are various sorts to pick from, including several "special" types you've probably never seen before.

Here I am choosing the temperature in degree Celsius as a variable type

After you've chosen a type, you'll see the variable declaration printed below it, in the same format as an Arduino project.

The variable permission must be addressed next. Here you have two options:

read and write

Only read

You'll need to pick Read & Write for an LED because you'll need to be able to write to it to control it. If this had been a sensor like our DHT-11 read-only would work.

Finally, there's the Update Policy variable. You have two options once more:

On change — When something changes, update the variable.

Periodically - Update the variable after a set amount of time has passed.

Do the same thing for the humidity variable

Write the name of the variable as humidity and then select the variable type relative humidity

And click on add variable.

after that add the last variable that is message ad select the variable type as a character string.

Adding the device

How to add the device in Arduino IoT cloud

Now click on the Setup 3^rd party device

SSelect the esp32 dev module

Next, rename the device

By default, Arduino IoT cloud selects the name of the board also you can write your name of the board.

You'll now be provided with a screen that reads "Secret Key." You'll need to copy this key because it's the only place you'll see it. You can copy it by clicking the symbol next to it or downloading the key as a PDF document.

After you've double-checked that you have a copy of the secret key, you can go to the next step. Your ESP32 configuration will be finished.

It's now time to configure your network credentials. In the Network section, click the Configure button.

You'll notice that instead of two parameters, you'll need to offer three parameters.

1. SSID name

2. SSID password

3. Secret key

Schematic [Esp32 & DHT11]

Connection:

Dht11 sensor has 4 pins that are VCC, DATA, NC, GND

Connect VCC pin to Vin pin of the esp32 board, data into digital pin 13 of the esp32, and GND pin to GND pin of the esp32 board.

Connect the esp32 board to your desktop with an appropriate MicroUSB cable once everything is connected.

Just click on sketch then

You'll be redirected to the simple sketch editor if you click the Sketch tab. You can continue working on your sketch here, or click the Open Full Editor button to launch a more powerful editor, akin to the Arduino IDE software.

Adding Arduino Sketch:

Simply click on the sketch and follow the prompts.

If you click the Sketch tab, you'll be sent to the simple sketch editor. You can either continue working on your sketch or click the Open Full Editor button to open a more capable editor, similar to the Arduino IDE software.

you need to do a few changes here like adding a library for the DHT-11 sensor.

The sketch framework is already developed, and it includes information about the cloud variable we just established in the header.

This variable is already defined in the thingProperties.h library, which is included with your sketch, so you don't need to specify it in your sketch. You may look at this file in the advanced editor; it contains definitions for your variable(s) as well as a declaration for a function connected with the variable change event. There's also information on the cloud and network connections.

you can copy the necessary part from the following code and paste it into your Arduino sketch and you are good to go

#include "arduino_secrets.h"

Sketch generated by the Arduino IoT Cloud Thing "Temperature and Humidity monitoring"

https://create.arduino.cc/cloud/things/b03581ea-7134-40e3-92db-cffc33abfa0b

Arduino IoT Cloud Variables description

The following variables are automatically generated and updated when changes are made to the Thing

CloudRelativeHumidity humidity;

String msg;

CloudTemperatureSensor temperature;

Variables which are marked as READ/WRITE in the Cloud Thing will also have functions

which are called when their values are changed from the Dashboard.

These functions are generated with the Thing and added at the end of this sketch.

#include "thingProperties.h"

#include "DHT.h"

#define DHTpin 13 // D4 on the nodemcu ESP8266

#define DHTTYPE DHT11

DHT dht(DHTpin,DHTTYPE);

void setup() {

// Initialize serial and wait for port to open:

Serial.begin(9600);

// This delay gives the chance to wait for a Serial Monitor without blocking if none is found

delay(1500);

// Defined in thingProperties.h

initProperties();

// Connect to Arduino IoT Cloud

ArduinoCloud.begin(ArduinoIoTPreferredConnection)

The following function allows you to obtain more information

related to the state of network and IoT Cloud connection and errors

the higher number the more granular information you’ll get.

The default is 0 (only errors).

Maximum is 4

setDebugMessageLevel(2);

ArduinoCloud.printDebugInfo();

}

void loop() {

ArduinoCloud.update();

// Your code here

float hm= dht.readHumidity();

Serial.print("Humidity ");

Serial.println(hm);

float temp=dht.readTemperature();

Serial.print("Temperature ");

Serial.println(temp);

humidity=hm;

temperature=temp;

message="Temperature = " + String (temperature)+" Humidity = " + String(humidity);

}

Since Humidity is READ_WRITE variable, onHumidityChange() is

executed every time a new value is received from IoT Cloud.

void onHumidityChange() {

// Add your code here to act upon Humidity change

}

Since Msg is READ_WRITE variable, onMsgChange() is

executed every time a new value is received from IoT Cloud.

void onMsgChange() {

// Add your code here to act upon Msg change

}

void dht_sensor_getdata()

{

float hm= dht.readHumidity();

Serial.print("Humidity ");

Serial.println(hm);

float temp=dht.readTemperature();

Serial.print("Temperature ");

Serial.println(temp);

humidity=hm;

temperature=temp;

message="Temperature = " + String (temperature)+" Humidity = " + String(humidity);

}

d Creating Dashboard

The Dashboard is a graphical user interface that can be accessed via the web or a mobile application. Switches and displays can be added to the dashboard, and those features can be linked to variables that we have added.
To set the value of the temperature and humidity we will add the variable we generated for our Thing That variable will be used by the code we've uploaded to our Arduino to show the data on pin no 13 of esp32.

Click the Build Dashboard button on the Dashboard tab. The dashboard will be empty

The dashboard is blank and labelled "Untitled," and you'll need to switch to edit mode to change it .To enter edit mode, click the edit (pencil) symbol in the upper left corner.

You'll see an Add drop-down button once you're in edit mode. You'll be able to change the title of your dashboard as well.

The Add drop-down menu allows you to choose from a variety of Widgets, which are elements that you can place on your dashboard.

The first is a Switch, which appears to be a good choice for controlling an LED. When you select Switch, a new one will appear on your dashboard.

Now for monitoring the temperature we need to select the gauge widget and for humidity, we can percentage gauge or chart

To edit the Gauge, press the menu button on the Gauge. An editing window will appear.

You can give your gauge a name or leave it blank in this editor box. Because it displays temperature , I named it temperature

To link a cloud variable to the gauge, select Linked Variable. You'll be taken to a new window where you can link to an existing cloud variable.

I choose my Thing as well as the temperature variable. Then I selected Link Variable from the drop-down menu. And now gauge is successfully monitoring my temperature.

Now we will do the same thing for 2^nd parameter that we want to monitor that is

Humidity ,lets add percentage widget .

Then click on Link Variable and select the variable the drop-down menu. And now percentage widget is successfully link to humidity variable.

Interfacing of TMP36 Temperature Sensor with an Arduino in Tinkerad.

2021-12-04T22:01:00.002+05:30

Interfacing of TMP36 Temperature Sensor with an Arduino in Tinkerad.

This project will turn the Arduino into a thermometer! By using the tmp36 temperature sensor. We can able to measure our body temperature and turn on the 3 LEDs. Green LED indicates the low-temperature range, Yellow LED indicates the medium temperature range and Red LED indicates the high-temperature range. One can test the circuit starting the simulation, clicking on the sensor, then adjusting its temperature value using the slider, and can test the desired resulting LED patterns. For making the actual circuit, you need to use the Arduino, breadboard, USB cable, male-female jumper wires, three LEDs, three resistors (any value from 100-1K, 220 ohms), a TMP36 sensor,

Circuit Diagram:

Components Required:

§ Arduino UNO

§ TMP36 (Temperature sensor)

§ Resistor-03

§ LED – Green

§ LED – Yellow

§ LED – Red

§ Connecting wires

Connection:

The hardware a part of this project is quite simple and easy to place together. First of all, make the connections for the TMP36 sensor with the Arduino. The connections for the TMP36 sensor with the Arduino given in the above circuit diagram:

Connect the VCC pin of the TMP36 sensor to the 5V pin on the Arduino.

Connect GND pin of TMP36 sensor to the GND terminal of An Arduino.

Connect the green LED anode pin to pin no 4 of an Arduino

Connect the yellow LED anode pin to pin no 3 of an Arduino.

Connect the red LED anode pin to pin no 2 of an Arduino.

Connect the cathode of all the LEDs to the Arduino GND.

About TMP 36 Temperature Sensor:

The TMP36 temperature sensor is used to measure temperature using an Arduino in various applications! This sensor can measure a wide range of temperature range from -40°C to 125°C, and its low-cost sensor, making it a popular choice. TMP36 gives a voltage output that is straightaway proportional to the outside temperature. The TMP36 needs a very low voltage power supply to operate, it’s an accurate temperature sensor.

It won’t require any external calibration circuitry to give the accuracies of ±1°C at +25°C and ±2°C over the −40°C to +125°C temperature range. TMP36 creates a varying voltage output depending on the outside temperature it senses. It has three pins: one which is connected to the ground, another one connects to 5 volts, and a third one is the output pin which is connected to an analog input of an Arduino that is A0

Pinout:

Working of project:

As per the circuit diagram, the output voltage of the TMP36 is connected to the analog input pin of an Arduino. The analog Pin A0 reads the voltage and gives some analog value to Arduino. Or in simple words we can say the TMP36 sensor produces a changing voltage signal depending on the outside temperature it senses So, when temperature increases, the pin connected to A0 increases its voltage. And You can see in the circuit diagram that three LEDs are each connected to their digital pin.

This circuit operates in three mode

When the temperature is low it will turn on the green LED.

When the temperature medium it will turn on the yellow LED.

When the temperature is high it will turn on the red LED.

Code Explanation (Block Based):

First of all, we create a variable named temp, to store the temperature that is nothing but the sensor value to declare the variable click on the variable block and create a variable, see the below picture.

After declaring the variable drag out the set block and set to the following blocks

Step to set the variable to “map” or converting temperature into degree Celsius

Step 1: In the Math section, take out a "map" block, and merge two arithmetic blocks inside the first field.

Step 2: Set the temperature range -40 to 125.

Step 3: go to the Input section and take out an "analog read pin A0" block, and fix it into the first arithmetic block inside the "map" block.

Step 4: now set the math’s blocks to "(read analog pin A0 - 20) x 3.04".

After completing all steps, it should look like following picture

Take out the serial monitor block to print the temperature on the screen

[ Note: About an Arduino map function

The map function in Arduino is used to change one scale of values (that is analogue input values) into another scale of values, and a mainly it is use to read an analogue input which is 10 bit that is it converts varying voltage to 0 to 1023 using internal ADC (analogue to digital converter) and map function change the output to desired range of values.for ex.output values from 0 to 255.

Example “C” code:

/* Map an analog value to 8 bits (0 to 255) */

void setup() {}

void loop() {

int val = analogRead(0);

val = map(val, 0, 1023, 0, 255);

analogWrite(9, val);

}

For reference click here Arduino map function ]

Let’s use the main conditional statement of the program that is ‘if’ block

first if statement block:

In this if block we will use the less than “<” comparison operator.

Condition:

If the temperature value is less than 25 degree Celsius then pin 4 will be high and pin no 3 and pin no 2 will be Low. This will make green LED to turn on and other two LEDs will turn off this indicates the low temperature.

Second if statement block:

In this, if block we will use the three different operators two comparison operator that is less than “<” comparison operator and “>” greater than comparison operator and last the logical operator that is “&&” (and) operator

Condition:

If the temperature value is less than 50 degrees Celsius and If the temperature value is greater than 25 degrees Celsius then pin 3 will be high and pin no 4 and pin no 2 will be Low. This will make green-yellow LED turn on and other two LEDs will turn off this indicates the medium temperature.

Third if statement block:

Condition:

If the temperature value is less than 125 degrees Celsius and If the temperature value is greater than 50 degrees Celsius then pin 2 will be high and pin no 4 and pin no 2 will be Low. This will make the green-yellow RED turn on and the other two LEDs will turn off this indicates the high temperature.

[ Note:The logical operators return TRUE or FALSE, which are defined as 1 and 0, respectively, logical operators use where needs to make the decision based on multiple conditions.

&& is the logical and operator: it returns a true value only when if both the conditions are true and returns a false value when both the conditions are false]

Arduino Sketch:

int temp = 0;

void setup()

{

pinMode(A0, INPUT);

Serial.begin(9600);

pinMode(4, OUTPUT);

pinMode(3, OUTPUT);

pinMode(2, OUTPUT);

}

void loop()

{

temp = map(((analogRead(A0) - 20) * 3.04), 0, 1023, -40, 125);

Serial.println(temp);

if (temp < 25) {

digitalWrite(4, HIGH);

digitalWrite(3, LOW);

digitalWrite(2, LOW);

}

if (temp > 25 && temp < 50) {

digitalWrite(4, LOW);

digitalWrite(3, HIGH);

digitalWrite(2, LOW);

}

if (temp > 50 && temp < 125) {

digitalWrite(4, LOW);

digitalWrite(3, LOW);

digitalWrite(2, HIGH);

}

LED brightness control using Arduino and potentiometer in tinkercad

2021-03-02T15:33:00.003+05:30

LED brightness control using Arduino and potentiometer.

In this tutorial, we are controlling the LED brightness using the potentiometer. This is an easy tutorial for demonstrating how can we control the brightness of an LED or adjust the speed of a DC motor using Arduino Board, and potentiometer. in this tutorial we have used the three LEDs yellow, blue, green to control the brightness of the same.

Circuit Diagram:

Components Required:

§ Arduino UNO

§ Yellow LED

§ Blue LED

§ Green LED

§ Potentiometer 10K

§ Connecting wires

Connection:

The hardware part of this project is very simple and easy to place together. First of all, make the connections for LEDs with the Arduino.

Connect the anode of the yellow LED to the digital pin12 of an Arduino.

Connect the anode of the Blue LED to the digital pin 8 of an Arduino.

Connect the anode of the Green LED to the digital pin 4 of an Arduino.

Connect the cathode pin of all LEDs to the GND pin of an Arduino.

Let’s do the connection for the potentiometer now,

Connect the terminal-1 of the potentiometer to the GND of an Arduino.

Connect the terminal-2 of the potentiometer to the +5V of an Arduino.

Connect the middle terminal of the potentiometer to the analog input A0 of an Arduino.

What is a Potentiometer?

A potentiometer (also called the pot) it’s a 3 terminal variable resistor in which the resistance is manually controlled or varied by rotating the nob clockwise or anticlockwise. Thus by varying resistance, we can able to produce the changing voltage output.

Applications of Potentiometer:

following are the practical application of the potentiometer.

The pot is used as a voltage divider in many electronic circuitries.
The potentiometer is used in radio, television, and media players for volume control
Potentiometers are widely used in sound controls in various amplifiers.

Working on the project:

As per the circuit diagram, the output voltage of the potentiometer is connected to the analog input pin A0 of an Arduino. The potentiometer gives the Analog output when it is rotated. The output of the potentiometer is stored in a variable named inputval. Three LEDs are connected to the digital pin 12,8,4 respectively.

Whenever the pot rotated clockwise the output voltage increases thus the brightness of all three LEDs also increases.

Whenever the pot rotated anticlockwise the output voltage decreases thus the brightness of all three LEDs also decreases.

Arduino Code Explanation:

Define the LED and pot pin led1 is connected to pin 12, led2 is connected to pin 8, led3 is connected to pin 4, and the pot is connected to the analog input A0. Declare the variable name inputval and set it to “0”

int led1=12;

int led2=8;

int led3=4;

int pot=A0;

int inputval=0;

Inside the void setup, we will define the pin which are input and which are output pins, this set of code runs only once.

void setup()

{

pinMode(led1,OUTPUT);

pinMode(led2,OUTPUT);

pinMode(led3,OUTPUT);

pinMode(pot,INPUT);

}

the code inside the void loop runs over and over as long as the Arduino Board is turned on.

Here inside the loop store the pot value in the variable named potval.

void loop()

{

inputval=analogRead(pot);

analogWrite(led1,inputval);

analogWrite(led2,inputval);

analogWrite(led3,inputval);

delay (100);

}

Here we have to use the analogWrite function for all 3 LEDs to control the brightness.

The hardware a part of this project looks quite messy but if we go step by step its simple and easy to place together. First of all, we make the connections for the 7-segment display with the Arduino. The connections for 7-segments with the Arduino given in the above circuit diagram and below table.

7 segment display has 5 pins on upper side and 5 pins on downside.

Total 7-segment that is a,b,c,d,e,f,g see the picture below

Types of 7-segment display: there are two types of display available in market that is common anode and common cathode. In this tutorial we are using the common anode type of display.

There is bit difference in both the displays as their name suggest that the common cathode type of display has all the cathodes of the 7-segments connected at one place. And same for the common anode type of display the anodes of the 7-segments connected at one place.

1. The Common Cathode displays.

In the common cathode type of display, all the cathode connects together to logic “0” or GND. The individual segments are turned on using “HIGH”, or logic “1”.

The Common Anode displays

In the common anode type of display, all the anode terminals connected together to logic “1”. The individual segments are turned on using the, logic “0” or “LOW” digital signal.

Connection:

In this tutorial we are using common anode type of display.

Interfacing of IR receiver and IR Remote with an Arduino.

2021-03-02T14:57:00.003+05:30

Interfacing of IR receiver and IR Remote with an Arduino.

In this project, we will interface an IR Receiver and an IR Remote with an Arduino and controls the output devices that is LED and Buzzer.

An IR Receiver is an electronic device that emit light radiation and it receives the information in the form of light from IR Remote. The received information from the IR remote send it to the Microcontroller. There is various application of IR Receivers in day-to-day life like one used in TV remotes. When we pressed any key on the remote it generates infrared signals, IR receiver present in front of the TV receives that signal and send it to the microcontroller for decoding after this controller gives the required output. And also, main thing is it’s a wireless communication

Circuit Diagram:

Components Required:

§ Arduino UNO

§ IR Receiver

§ IR Remote

§ Red LED

§ Buzzer

§ Connecting wires

Connection:

The hardware a part of this project is quite simple and easy to place together. First of all, make the connections for the IR Receiver with the Arduino. The connections for the IR Receiver with the Arduino given in the above circuit diagram.

IR Receiver has three pins one is connected to the GND pin of an Arduino second pin is connected to the VCC pin of an Arduino and output pin of IR receiver is connected to the digital pin 10 of an Arduino.

Red LEDs Anode pin is connected to the digital pin 2 of an Arduino and cathode is connected to the GND Pin of an Arduino.

Buzzer positive pin is connected to the digital pin 3 of an Arduino and negative pin is connected to the GND pin of an Arduino Connect the one terminal of force sensor to the GND of an Arduino.

Basics of IR Communication

Infrared Communication or IR is using the Infrared Light. Infrared Light has wavelength which is higher than the visible light. Hence human being not able to see the Infrared Light.

This is the reason it is good choice for Wireless Communication. But is has disadvantage that is line-of-sight error which means for Communication between the transmitter and receiver both should be in one line. Due to this reason IR communication cannot be used through walls.

IR Receiver

let us take a brief about the IR Receiver that we are using here i.e.TSOP1838.

TSOP1838 is a very popular type of IR receiver and its carrier frequency of 38kHZ. It has three pins namely: GND, VCC and OUT.

The output of the TSOP 1838 IR Receiver can be directly decoded by a microcontroller.

Working of project:

The working of the remote controlled led and buzzer project is very simple. This project will demonstrate you how to interface IR Receiver and an IR Remote with an Arduino.

Whenever key “1” is pressed then red LED will flash and when the key “2” is pressed the buzzer will produce the sound. When we pressed the any key on the IR remote that decodes by the Micro-controller. Each key on the remote can be used for different task like turning on light, turn on motor etc.

Arduino Code Explanation:

Include the IR Remote Library after that define the output pin of IR Receiver it is connected to the pin 10 of an Arduino.

Define the LED and buzzer pins, led1 is connected to the pin 2 and buzzer is connected to the pin 3 of an Arduino.

#include <IRremote.h>

const int RECV_PIN = 10;

IRrecv irrecv(RECV_PIN);

decode_results results;

int led1=2;

int buzzer=3;

Inside the void setup we will define the pin which are input and which are output pin, this set of code runs only once.

Initialize the serial monitor for displaying the value at baud rate of 9600.

void setup(){

Serial.begin(9600);

irrecv.enableIRIn();

irrecv.blink13(true);

pinMode(led1,OUTPUT);

pinMode(buzzer,OUTPUT);

}

the code inside the void loop runs over and over as long as the Arduino Board is turned on.

Here inside the loop results.value stores the decoded code we can print that code on serial monitor as hex code using Serial.println(results.value, HEX);

Now for printing decimal value of the IR remote Key pressed for that we can use Serial.println(results.value);

void loop(){

if (irrecv.decode(&results)){

Serial.println(results.value, HEX);

irrecv.resume();

Serial.println(results.value);

}

if (results.value==16582903)

{

digitalWrite(led1,HIGH);

delay(200);

digitalWrite(led1,LOW);

delay(200);

}

if (results.value==16615543)

{

digitalWrite(buzzer,HIGH);

delay(200);

digitalWrite(buzzer,LOW);

delay(200);

}

Here wehave used if() conditional statement basic coding control structures. One can make something happen or not, it depends whether the condition is true or not. It looks like this:

When we pressed the “1” key on the IR remote then Arduino gives us the decimal output which is stored in results.value and the decimal output is 16582903.

If the if (results.value==16582903) then will create a led flashing effect by turning it on and off.

Same thing for the buzzer as well when we pressed the “2” key on the IR remote then Arduino gives us the decimal output which is stored in results.value and the decimal output for key 2 is 16615543.

If the if (results.value==16615543)then turn on the buzzer.

Watch the Working video:

Interfacing of tilt sensor (SW200D) with an Arduino in tinkercad.

2021-03-02T14:45:00.003+05:30

Interfacing of tilt sensor (SW200D) with an Arduino in tinkercad.

A Tilt Sensor can detect the inclination of an object and gives its output High or Low. There is a mercury ball inside the tilt sensor which moves when the sensor tilted and completes the circuit. So we can use this feature to turn on and off the circuit.

In this project, we are interfacing Tilt sensor with Arduino board in tinkercad. And controlling a LED output when the tilt sensor tilts. It can be used like an alarm if the sensor tilts then we can turn on the buzzer and LED flasher.

Circuit Diagram:

Components Required:

§ Arduino UNO

§ Tilt sensor (SW200D)

§ Resistor-1

§ LED-01

§ Connecting wires

Connection:

The hardware a part of this project is quite simple and easy to place together. First of all, make the connections for the tilt sensor with the Arduino. The connections for the tilt sensor with the Arduino given in the above circuit diagram.

The tilt sensor we used here is SW200D.tilt sensor has two pins one is connected to the GND pin of an Arduino and another pin is connected to the digital pin of an Arduino.

Connect the one terminal of tilt sensor to the digital pin 2 using resistor.

Connect the other terminal of tilt sensor to the GND pin of an Arduino.

Connect the LEDs anode terminal to digital pin 9 of an Arduino.

Connect the LEDs cathode terminal to GND pin of an Arduino.

Working of Arduino Tilt Sensor

A Tilt sensor is quite similar to a normal on off switch only difference is it conducts current when it inclined at certain angle or in other words, I can say it turned on only when it tilts. Due to this property, we can use tilt sensor to detect the orientation od an object.

Now there are different types of tilt sensor out there here we using a simple one axes inclination, a tilt switch or sensor. There are two kinds of technology is to make the tilt sensor Mercury based and Roller Ball based. The old ones are made of mercury. For more accuracy and results we are having an accelerometer based 3- axis tilt sensor, using this sensor we can detect full motion in three axes.

In SW200D tilt sensor, two metal balls are used to close or open the switch. When we placed the sensor in upright position then metal ball closes the contact with both the terminal and closes the switch.

When the inclination of the sensor is changed or sensor is tilted by certain angle then metal ball are not in contact with terminal then the switch is open.

Working of project:

As per the circuit diagram, the output voltage of the tilt sensor is connected to the digital input pin 2 of an Arduino. Tilt sensor gives the digital output when it tilted. output of the tilt sensor is stored in variable name tilt sensor. Now if the tilt sensor output is high that is 1 then set the digital pin 9 low this will make LED turn off, if the tilt sensor output is low that is 0 then it gives the led flasher effect.

Code Explanation (Block Based):

First of all, we create a variable named tilt_sensor to store the sensor value . For declare the variable click on the variable block and create a variable, see the below picture..

After declaring the variable drag out the set block and set to the following blocks

Now set the variable that is tilt_sensor to the read digital pin 2.

Take out the serial monitor block to print the sensor value on the screen

Let’s use the main conditional statement of the program that is ‘if’ block

Drag the if block from the control also drag one block that is set pin block from output and place it inside the if block. Select the digital pin 9 drag the comparator operators from operators from math’s block. Here two conditional statements used,

Condition1:

If the tilt sensor value is equal to the 1 then set digital pin 9 low, this will make LED turn off.

That means sensor is not tilted.

Condition2:

If the tilt sensor value is equal to the 0 then set digital pin 9 high for 0.2 sec and low for 0.2 sec this will create the LED flasher effect. Indicate that sensor is tilted.

Watch Working video :

Complete Arduino sketch:

int tilt_sensor = 0;

void setup()

{

pinMode(2, INPUT);

Serial.begin(9600);

pinMode(9, OUTPUT);

}

void loop()

{

tilt_sensor = digitalRead(2);

Serial.println(tilt_sensor);

if (tilt_sensor == 1) {

digitalWrite(9, LOW);

}

if (tilt_sensor == 0) {

digitalWrite(9, HIGH);

delay(200); // Wait for 200 millisecond(s)

digitalWrite(9, LOW);

delay(200); // Wait for 200 millisecond(s)

Interfacing of force sensor (FSR)with an Arduino in tinkercad

2021-02-15T10:34:00.001+05:30

Interfacing of force sensor (FSR)with an Arduino in tinkercad

In this project we will be interfacing the Force sensor or force sensing resistor (FSR) to the Arduino Uno. Also, we have interface three different LEDs with Arduino.

in this tutorial you will learn how the force sensor works and how to interface with Arduino in tinkercad. The force is use to detect the pressure, amount of weight applied on the sensor, there are many applications of force sensor like it is used in electronic drum, gaming devices, industrial electronics etc. These sensors are good for measuring pressure but not highly accurate for measuring the weight.

Circuit Diagram:

Components Required:

§ Arduino UNO

§ Force sensor

§ Resistor-01

§ Red LED

§ Yellow LED

§ Blue LED

§ Connecting wires

Connection:

The hardware a part of this project is quite simple and easy to place together. First of all, make the connections for the force sensor with the Arduino. The connections for the force sensor with the Arduino given in the above circuit diagram.

The force sensor we used here has size 2 inch. force sensor has two pins one is connected to the GND pin of an Arduino and another pin is connected to the digital pin of an Arduino using the voltage divider across this pin.

Connect the one terminal of force sensor to the GND of an Arduino.

Connect the other terminal of FSR to resistor for creating the voltage divider.

Connect the voltage divider output is connected to the analog input pin A0 of an Arduino.

Connect the red LED anode pin to digital pin 5.

Connect the yellow LED anode pin to digital pin 4.

Connect the blue LED anode pin to digital pin 3.

Connect the cathode pin of all LEDs to the GND pin of an Arduino.

FSR Overview

Force Sensor also known as Force Sensing Resistors (FSRs). These sensors are cheaper compare to others and easy-to-interface with the microcontroller.

The kind of technology is used by FSRs has been patented by Interlink Electronics. There are two common types of FSR available FSR-402 and FSR-406, in market you will find the two different size and shape FSR pictures given below.

Two kinds of FSR based on shape one is a circular and another one is rectangular sensing area. Rectangular FSR used to sense the large area, while small circular sensors are used sense small

area with good accuracy.

How FSR Works?

FSR is a kind of variable resistor whose value depends upon the pressure applied to the sensor.

When there is little pressure or no pressure, then sensor gives the high resistance output. Harder you apply the pressure on the sensor, lower the resistance value you get, and as soon as you remove the pressure it will get back to its original value that is high resistance.

How to take reading of an FSR?

We can easily read the FSR by creating the voltage divider across the FSR. For crating voltage divider, we will connect fix value resistor (10kΩ) to one terminal of an FSR. After that connect the fixed value resistor and the variable FSR resistor to the analog input pin of an Arduino that is pin A0. This is how creating voltage divider we can able to read the variable voltage output.

Working of project:

As per the circuit diagram, the output voltage of the FRR is connected to the analog input pin A0 of an Arduino. FSR gives the Analog output when it is pressed. The output of the FSR is stored in variable named forcesense. Three LEDs are connected to the digital pin 5,4,3 respectively.

This circuit operates in three mode

When the very little force is applied on the sensor then blue LED will turn on. is low it will turn on the green LED.

When the applied force is in between high and low the yellow LED will turn on.

When the very high force is applied on the sensor then red will turn on.

Code Explanation (Block Based):

First of all, we create a variable named forcesense to store the sensor value . For declare the variable click on the variable block and create a variable, see the below picture..

After declaring the variable drag out the set block and set it to the read analog pin A0.

Take out the serial monitor block to print the sensor value on the screen

Let’s use the main conditional statement of the program that is ‘if’ block

first if statement block:

In this if block we will use the less than “<” comparison operator.

Condition:

If the FSR value is less than 30 then pin 5 will be and pin no 4 and pin no 3 will be Low. This will make blue LED to turn on and other two LEDs will turn off this indicates the low pressure applied.

Second if statement block:

Condition:

If the applied force value is less than 220 and also If the applied force value is greater than 90 then pin 4 will be high and pin no 5 and pin no 3 will be Low. This will make yellow LED turn on and other two LEDs will turn off this indicates the medium range force is applied on FSR.

Third if statement block:

Condition:

If the applied force value is less than 1023 and also If the applied force is greater than 220 then pin 3 will be high and pin no 5 and pin no 4 will be Low. This will make the red LED turn on and the other two LEDs will turn off this indicates the high force applied on the FSR.

[ Note:The logical operators return TRUE or FALSE, which are defined as 1 and 0, respectively, logical operators use where needs to make the decision based on multiple conditions.

&& is the logical and operator: it returns a true value only when if both the conditions are true and returns a false value when both the conditions are false]

A basic gas sensor has 6 terminals in which 4 terminals (A, A, B, B) acts as input or output and the other 2 pins (H, H) are for heating the coil.

Connect the A1, H1, A2 to the power pin of an Arduino.

Connect the B1 to the analog pin A5 of an Arduino.

Connect the h1 to the GND pin of an Arduino.

Connect the B1 to the GND through resistor.

Connect the buzzer positive pin to digital pin 10 of an Arduino.

Connect the LED with resistor to digital pin 11 of an Arduino.

Connect the LED with resistor to digital pin 12 of an Arduino.

Connect the negative of the buzzer and cathode of LED to the GND pin of an Arduino.

What is MQ2 Gas Sensor?

MQ2 gas sensor is one of most used in MQ sensor list. It is a Metal Oxide Semiconductor (MOS). Gas sensor is one which use to detect the variation in the concentration of toxic gases in environment, industries in various places.

How does it work?

Sensor gives the analog output that is changing voltage output based on smoke/gas level that exists in the atmosphere. The sensor outputs a voltage that is proportional to the amount of concentration of smoke/gas in the environment.

In simple words, I can put the relationship between voltage and gas concentration is the following:

§ If there is more the gas concentration, the more the output voltage

§ lesser the gas concentration, the lesser the output voltage

List of Gas Sensors and What Gases They Sense

Arduino Code Explanation:

Define the LED and buzzer pins, led1 is connected to the pin 12 and led2 is connected to the pin 11 and last buzzer is connected to the pin 10.

Ø int led1=12;

Ø int led2=11;

Ø int buzzer=10;

define where the gas sensor is connected, it is connected to the analog pin A5 of an Arduino.

Ø int gas_sensor=A5;

declared variable named sensorthreshold to store the threshold value of gas sensor

Ø int sensorthreshold=600;

Inside the void setup we will define the pin which are input and which are output pin, this set of code runs only once.

Initialize the serial monitor for displaying the value at baud rate of 9600.

void setup()

{

pinMode(led1,OUTPUT);

pinMode(buzzer,OUTPUT);

pinMode(gas_sensor=A5,INPUT);

Serial.begin(9600);

}

the code inside the void loop runs over and over as long as the Arduino Board is turned on.

Here inside the loop defined one variable called analog sensor to store the gas sensor value

void loop()

{

int analogsensor=analogRead(gas_sensor);

Serial.println("sensor ");

Serial.println(analogsensor);

The if() conditional statement basic coding control structures. One can make something happen or not, it depend whether the condition is true or not. It looks like this:

If the value stored in analogsensor variable is greater than threshold value then led1 will tun on and buzzer start producing sound

if (analogsensor>sensorthreshold)

{

digitalWrite(led1,HIGH);

digitalWrite(led2,LOW);

tone(buzzer,1000,350);

}

If the exact opposite happens then led2 will turn on and buzzer turned off.

else

{

digitalWrite(led1,LOW);

digitalWrite(led2,HIGH);

noTone(buzzer);

}
