Picture of Arduino Motor Control Kit
The aim of this project is to make a Arduino Motor Control Shield, that is cheap, ergonomic and easy to make. I was thinking, why not use cardboard instead of a pcb, after all its easy to use for almost everyone!

The Motor plugs into the green screw terminals, and the shield is powered by 1 9V battery. You could also stack 2 shields and share one battery to power 2 motors without bulk.

So here is what you need. About 5$ max in parts from Radio Shack

1 Transistor (I use 2N2219)
100 OHM Resister
1 Piece Cardboard
1 Screw Terminal
1 9V Snap
Misc Wire
Basic Soldering Stuff

I wouldn`t ignore the diode if you want the transistor to work for long.

the code you posted is only turning the motor on.

this code with put the motor at 100%, 50%, 0% :)

int motorPin = 11;

void setup() {

pinMode(11, OUTPUT);

void loop()
analogWrite(motorPin, 255); // Motor 100%
analogWrite(motorPin, 127); // Motor 50% (almost)
analogWrite(motorPin, 0);; // Motor 0%

are u an Indian??
