Stepper Motor Controller - Part 2

Continuing our saga from Part 1, We finished soldering up the controller shield with all the components. We have downloaded the library, and have connected the stepper motor. The motor has 4 wires, which we have attached to the M1/M2 connector. The wires connect top to bottom:

1. Orange
2. Yellow
3. N/C
4. Green
5. Brown

A 12v power supply connects to the motor external power connector. Make sure you do not enable the Arduino power jumper just to the right of the motor external power connector.

Code:

#include <AFMotor.h>


AF_Stepper motor(48, 1);


void setup() {

  motor.setSpeed(10);  // 10 rpm   

  motor.step(100, FORWARD, SINGLE); 
  motor.release();
  delay(1000);
}

void loop() {
  motor.step(100, FORWARD, SINGLE); 
  motor.step(100, BACKWARD, SINGLE); 

  motor.step(100, FORWARD, DOUBLE); 
  motor.step(100, BACKWARD, DOUBLE);

  motor.step(100, FORWARD, INTERLEAVE); 
  motor.step(100, BACKWARD, INTERLEAVE); 

  motor.step(100, FORWARD, MICROSTEP); 
  motor.step(100, BACKWARD, MICROSTEP); 
}
