transistor

This is a creation of working breadboard and we used the two straps for power. and we used the transistor to accelerate some power that is flowing through the breadboard.

Robot 1

These pictures are from when we made our robot in class and we used the motor in order to power the wheels and make the robot move back and forth. Also we used several resistors in order to resist some of the energy from the initial current, because if we did not we could seize something and create a malfunction. We also used an object on the front which detects things within 6 inches of the robot and tells the robot to turn right or left. Underneath you may notice a battery that we attached and eventually hook the bread board up to so that we had power. We not only had to program this robot but we also had to envision the aftermath, when the project was complete and i successfully created a code that gave my moving robot distinct functions.

LED light

This is the bread board programed by arduino and we attached

a LED light and a button to control that light, this while be useful

for my robot in the future.

Sonar

This is a sonar senor and it is useful because it can detect how far thing are away form it.
This will help my robot avoid immediate objects.

Stepper motor attached to bread board

This is the stepper motor hooked up to the bread board and also a relay is attached we use both of these
in in cases like moving things back and forth.

Resistor

This is when we tested the voltage of the resistor by touching the red and black cords to opposite ends or the resistor. This is extremely helpful when you need to test a resistor so that you can properly run your robot.

Switch

This motor(actuator) functions in two different ways, back and forth and

the switch on the left hand side controls that operation.

the motor

This is a bread board (programed by arduino) and we created this bread board to propel energy through itself and the motor(placed on the bottom right hand corner) We use this motor in order to help our future robots to make the wheel move etc.

Electric circuits

noreply@blogger.com (Brandon M.) — Mon, 23 Jan 2012 11:33:00 +0000

Both these circuits turn on an LED when a button is pressed.
One circuit is simple. It uses no microcontroller. When the momentary push-button is
pressed, the circuit is completed, and the LED turns on. We use a 220 Ohm resistor
with the LED because otherwise, the LED would burn out.
The second circuit uses a programmable microcontroller.
The LED that is turned on/off is permanently connected through a resistor to the
microcontroller board at pin 13.
The momentary push-button is connected to digital pin 2 and 5v.
Digital pin 2 is also connected to GND via a 10k resistor.
If the resistor were not there, the LED might flicker as a result of the pin “floating”.
“Floating” means that the pin is neither connected to GND nor to 5v when the button
is not pressed. A “floating” pin may lead to a flickering LED.
Therefore, pin 2 has to be connected to GND through a resistor. This will cause the
pin to sense GND when the button is not pressed, and 5v, when it is pressed.
The program uploaded to the microcontroller creates the connection between the
state of the button (on/off) and the state of the LED (on when button is pressed, off
when it is not pressed).
