L298N Dual H Bridge DC Stepper Motor Controller Module for Arduino

/* 

 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.
