Software

We'll use the built-in Arduino Stepper library (http://adafru.it/eRw), but you can manually

toggle the AIN1/AIN2/BIN1/BIN2 pins with your own favorite microcontroller setup

#include <Stepper.h>

// change this to the number of steps on your motor

#define STEPS 200

// create an instance of the stepper class, specifying

// the number of steps of the motor and the pins it's

// attached to

Stepper stepper(STEPS, 4, 5, 6, 7);

void setup()

{

Serial.begin(9600);

Serial.println("Stepper test!");

// set the speed of the motor to 30 RPMs

stepper.setSpeed(60);

}

void loop()

{

Serial.println("Forward");

stepper.step(STEPS);

Serial.println("Backward");

stepper.step(-STEPS);

}

Basically after you make the Stepper object with the 4 control pins, you can set the

rotational speed (in RPM) with setSpeed(rpm) and then step forward or backwards with

.step(steps) where steps is positive for 'forward' and negative for 'backward'
