Run this example from the command line with:

node eg/stepper-driver.js
var five = require("johnny-five");
var board = new five.Board();

board.on("ready", function() {

  /**
   * In order to use the Stepper class, your board must be flashed with
   * either of the following:
   *
   * - AdvancedFirmata https://github.com/soundanalogous/AdvancedFirmata
   * - ConfigurableFirmata https://github.com/firmata/arduino/releases/tag/v2.6.2
   *
   */

  var stepper = new five.Stepper({
    type: five.Stepper.TYPE.DRIVER,
    stepsPerRev: 200,
    pins: {
      step: 11,
      dir: 13
    }
  });

  // Make 10 full revolutions counter-clockwise at 180 rpm with acceleration and deceleration
  stepper.rpm(180).ccw().accel(1600).decel(1600).step(2000, function() {

    console.log("Done moving CCW");

    // once first movement is done, make 10 revolutions clockwise at previously
    //      defined speed, accel, and decel by passing an object into stepper.step
    stepper.step({
      steps: 2000,
      direction: five.Stepper.DIRECTION.CW
    }, function() {
      console.log("Done moving CW");
    });
  });
});
