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.

Step 1: Parts List!

Picture of Parts List!
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

Step 2: Cut The CardBoard

Put the cardboard on the Arduino and cut out a shape that fits on like a shield, put 2 dots, one for ground and one at an digital PWM Pin, then punch out the holes.

Step 3: Wiring!

Picture of Wiring!
Put the parts through the cardboard, and wire it up in the back(IGNORE THE DIODE) , test then solder

Make sure the output pins fit when put on the arduino

Step 4: Programming

Here comes the fun part!

Screw in you motor, and attach your shield to the Arduino

If you dont want to figure out this yourself, then here is a simple code I made for you guys:


int rowPin1 = 11

void setup() {
pinMode(rowPin1, OUTPUT);

void loop()
digitalWrite(rowPin1, HIGH);
digitalWrite(rowPin1, HIGH);
digitalWrite(rowPin1, HIGH);

what is the resister for

Very interesting.

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

Thanks man

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??
