Tutorial(our version does not have the aluminum case)

Connect a power supply from 10-36V to the Driver Module GND and +36v terminal pins.

Example Code using the Accelstepper library:

#include <AccelStepper.h>

// Define a stepper and the pins it will use
AccelStepper stepper(1, 2, 3); // 1 = Driver Mode, Step = pin 2, Direction = pin 3

void setup()
{
stepper.setMaxSpeed(3000.0);
stepper.setAcceleration(3000.0);
}

void loop()
{
stepper.runToNewPosition(0);
stepper.runToNewPosition(5000);
stepper.runToNewPosition(1000);
stepper.runToNewPosition(1200);
}
