/* 
 Stepper Motor Control - one revolution
 
 Revisionato per i motori 5v 28YBJ-48 con controller board
 - http://arduino-info.wikispaces.com/SmallSteppers
 
 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.
