New Stepper Motor Example code that works

code: [select]

/*
  stepper motor control - 1 revolution

  program drives unipolar or bipolar stepper motor.
  motor attached digital pins 8 - 11 of arduino.

  motor should revolve 1 revolution in 1 direction, then
  1 revolution in other direction.

#include <stepper.h>

const int stepsperrevolution = 2048;  // change fit number of steps per revolution motor

// initialize stepper library on pins 8 through 11:
stepper mystepper(stepsperrevolution, 8,  10, 9, 11);

void setup() {
  // set speed @ 10 rpm: (15 or less motors , controllers)
  mystepper.setspeed(10);
  // initialize serial port:
  serial.begin(9600);
}

void loop() {
  // step 1 revolution  in 1 direction:
  serial.println("clockwise");
  mystepper.step(stepsperrevolution);
  delay(50);

  // step 1 revolution in other direction:
  serial.println("counterclockwise");
  mystepper.step(-stepsperrevolution);
  delay(50);
}

changes: changed stepsperrevolution more in line current stepper motors
             changed initiating stepper class - pins changed reflect stepper motor driver pin out documentation
             changed stepperspeed 10 motors kits don't work on 15 rpm
             changed delay 50. 500ms long.
