 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.

//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
//OK alim via uniquement USB, 200mA
#include <Stepper.h>

// for your motor
// initialize the stepper library on pins 8 through 11:
Stepper myStepper(stepsPerRevolution, 8, 9,10, 11);
void setup() {
  // set the speed at max 14t/mn
  myStepper.setSpeed(3);
  // initialize the serial port:
  Serial.begin(9600);
