 Stepper Motor Control - one step at a time
 This program drives a unipolar or bipolar stepper motor.
 The motor is attached to digital pins 8 - 11 of the Arduino.
 The motor will step one step at a time, very slowly.  You can use this to
 test that you've got the four wires of your stepper wired to the correct
 pins. If wired correctly, all steps should be in the same direction.

 //Moteur 28BY H 48, 8 dents , 4steps par tour soit 32steps/tour, 11.25° /step
//MAIS reduction mecanique de 64 donc il faut 32*64= 2048 steps /tour d'axe externe
//freq max 100Hz soit 10ms /step mini, 20480ms/tour au plus vite: 20s/t = 3 tr/mn max
//en pratique, supporte 14t/mn grand maximum!
//OK via USB, 200mA
