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.

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%
delay(5000);
analogWrite(motorPin, 127); // Motor 50% (almost)
delay(5000);
analogWrite(motorPin, 0);; // Motor 0%
delay(2500);

}
