It has been a long long time since I posted a new project on our website. Today I looked in to all my old emails and checked all pending projects which were not uploaded. I want to thank Gaurav Sharma for submitting this wonderful project. I Hope to see more contribution from him.

Metro Train is one of the biggest transporation medium in Delhi connecting all ends of Delhi together. This project is a very simple train prototype of current Metro Train. This prototype is powered with 8-bit 8051 microcontroller. As you know Metro trains run in one direction at a time, so prototype uses only one motor to move the forward. There is an additional motor which is used to open and close the doors of train. LCD is used to display welcome message, current station and next station messages. A buzzer is there to indicate opening and closing of doors.

Working Of Metro Train:

When the power is turned on a message ("welcome to Bhopal metro") is displayed on LCD. Then a message "Current station is Indrapuri" is displayed and door is opened. A buzzer is also turned on when door opens. After some delay the door is closed and car is started to move forward. A message "current station is Indrapuri" is displayed also on LCD. After some time a message indicating the next station is displayed "next station is M P Nagar". After some time the train stops and a message "current station is M P Nagar" is displayed. This process is continued for five stations. In the end a message "End of line" is displayed on LCD. This whole process is repeated until we turned off the power supply.

A big thanks to Gaurav Sharma for submitting this project.

The digital IC tester is implemented by using the 89C51 microcontroller board. The processing of the inputs and outputs is done by the microcontroller. The display part on the microcontroller board is modeled using LCD. After the successful testing of the IC, the result is displayed on the LCD.

The basic function of the digital IC tester is to test a digital IC for correct logical functioning as described in the truth table and/or function table. It can test digital ICs having a maximum of 24 pins. Since it is programmable, any number of ICs can be tested within the constraint of the memory available. This model applies the necessary signals to the inputs of the IC, monitoring the outputs at each stage and comparing them with the outputs in the truth table. Any discrepancy in the functioning of the IC results in a fail indication, displays the faulty and good gates on the LCD. The testing procedure is accomplished with the help of keys present on the main board.

This project has been tested with most commonly used digital IC's, mainly belonging to the 74TTL series. Digital IC tester tests various types of IC's like OR, XOR, NAND, AND, NOT, NOR, XNOR GATES and also FULL ADDER, MULTIPLEXER, SHIFT REGISTER.

This project is a simple GSM Based project where 20x4 LCD is used as display for Notice board and GSM modem is used for receiving and sending SMS. When a user wants to display a notice/message on the notice board, user will send sms from a verified mobile number and sms recevied is displayed on LCD. Project involves simple security feature where SMS sender's number is compared with a pre-configured number (hardcoded in source code). If sms is recevied from an unknown sender, a notification SMS is sent to pre-configured number notifying an invalid access to board.

This project is fairly simple but its main purpose is to demonstrates reading and sending SMS using GSM Modem. There are many users on forum who struggles getting SMS read working in their projects. So For them this project is a starting point.

I want to thank Kiran Gowle (kirangowle) for submitting this project. I am sure his contribution will help many others on this website. If you have any queries regarding this project, Please feel free to post in forum.

Our robot expert Gaurav Khadasane has come up with another innovative way to control a robot. He is controlling his robot from an android phone (with a Android GUI application) over bluetooth. Project uses our favourite 8051 microcontroller and HC-05 bluetooth module.

In this project 8051 and bluetooth module are communicating over uart @9600bps. Bluetooth module HC-05 is controlled via simple AT commands. This module comes in SMD package and works on 3.3v power supply. The BT module is a SPP supported profile so it can be connected easily to any controller or embedded device. In this profile the data sent and receive to module directly comes on the RX pin of microcontroller. It becomes really easy to make your device bluetooth compatible.

L293D H-Bridge motor driver are used to control two DC motors. A readymade compact size chassis is used to avoid the chassis assembly comlexities

The chassis contains 2 decks the lower is used for BO motors fitting the upper is used as a battery stack. On top plate the controller board is mounted by screw fitting.

Finally the Android application, You can get Bluecontrol app from Google Play

This project is an extention to previously uploaded "GSM Controlled Robot". Earlier project was only designed to be controlled using a mobile or GSM device whereas this project extends the control capabilities to custom designed RF Remote and A glove with Accelerometer.

This project is devided into two sections
1. Control/Encoder unit
2. Robot Unit

Control unit uses 433Mhz RF modules for sending control data to robot. Control unit receives data from either remote or an accelerometer module. Robot unit is actually the receving device which can receive data from either gsm device or RF recevier. Both RF reciever and GSM device send same kind of signals to control motors.

Control/encoder unit uses 8051 controller and its code is written in assembly whereas Robot unit uses AVR microcontroller, its source is written in C language. If you have already built the old GSM controlled robot then upgrading to this version of robot will not be difficult at all.

I have also added original project report came with GSM controlled robot, You can add more information in this project report to complete final report.

Hi Friends, Its been a long time since I've been to website. But There were few main things that I was suppose to do a long time back. Here is a new year surprise for you all. Viktor has share another project with us a great design with practical use. An 8051 based Solar tracker with source written in assembly language. Viktor explains basic operation of this project.

PRINCIPLE OF OPERATION
The circuit comprises of three sections:

light controlled circuit
counter for timer
switching circuit

1. Light controlled circuit:

This particular circuit controls other circuits. It puts the other circuit on or off depending the nature of the day. It comprises of LDR and transistor representation of smith trigger configured using two npn transistor(BC377) such that when there is a small potential difference across the LDR and variable resistor, The relay will be triggered to switch on other circuit. This circuit monitors day and night. The main function of this monitor is put off the device at night and turn it on in the mornining again.

2. counter for timer:
Since sun start from the east at 6:45am and set at exertly 12:45pm, the light controller circuit put on the whole circuit automatically making the timer to initialize its 6hrs counting sequence.

3. switching circuit:
This circuit is mainly used to control the direction of panel using a DC Actuator motor. Microcontroller AT89C2051 gets input from east and west Light control circuit and adjust panel to face sun direction.

Type of motor used:
24-36v d.c Actuator from super jack used in tv satalite dish polar adjustment

Well this is one of the most interesting and long awaited project uploaded on any microcontroller website. Its an Inverter/UPS with inbuilt charging system based on 8051 (AT89C2051) with a rating of 3000VA. As you all know an inverter converts DC voltage to AC, This project uses 24V DC battery and convert it to 220v 50Hz AC. Here are some pictures of constructed hardware.

The inverter system is divided into six sections:

Inverter
Charger
Multivibrator
Powerpack
Sensors and Indicators
Automatic changeover

8051 controller plays its major role in "Sensors and Indicators" section. 8051 is used to monitor the voltages and indicate status through LEDs. You can also find UPS test design for Proteus VSM simulator, to stimulate the design in case of any doubt. It is the same controller circuit as given in pdf. At89c2051 uses an active low to perform its operation from lm393 voltage comparator that's why a push button is connected to ground to test the circuit.

You can find pictures, code and small documenation that explains the working and block diagram of this project. Incase you have any doubts, feel free to post on our forum at www.8051projects.net/forum.html

This Project "Automatic Room Light Controller with Visitor Counter using Microcontroller" is a reliable circuit that takes over the task of controlling the room lights as well us counting number of persons/visitors in the room very accurately. When somebody enters into the room then the counter is incremented by one and the light in the room will be switched ON and when any one leaves the room then the counter is decremented by one. The light will be only switched OFF until all the persons in the room go out. The total number of persons inside the room is also displayed on the seven segment displays.

The microcontroller does the above job. It receives the signals from the sensors, and this signal is operated under the control of software which is stored in ROM. Microcontroller continuously monitor the IR Sensors, When any object pass through the 555 timer generates a pulse and interrupt controller. So visitors in the room are counted up by Sensor1 and Sensor2 counts visitors going out of room. As soon as visitor count reaches 0 the room light turns off.

We already had this project in our download section but Anudeep (bobdxcool) had made it working. Thank you so much for sharing this project back.
