  Stepper Motor Control - one revolution

  This program drives a unipolar or bipolar stepper motor.
  The motor is attached to digital pins 8 - 11 of the Arduino.

  The motor should revolve one revolution in one direction, then
  one revolution in the other direction.

// for your motor

// initialize the stepper library on pins 8 through 11:

void setup() {
  // set the speed at 60 rpm:
  myStepper.setSpeed(30);
  // initialize the serial port:
