var five = require("../lib/johnny-five.js"),

board = new five.Board();

board.on("ready", function() {
  // Create a new `motor` hardware instance.
  motor = new five.Motor({

  });

  // Inject the `motor` hardware into
  // the Repl instance's context;
  // allows direct command line access
  board.repl.inject({

  // Motor Event API

  // "start" events fire when the motor is started.
  motor.on("start", function() {
    console.log("start", Date.now());

    // Demonstrate motor stop in 2 seconds
    board.wait(2000, function() {

    });
  });

  // "stop" events fire when the motor is stopped.
  motor.on("stop", function() {
    console.log("stop", Date.now());
  });

  // Motor API

  // start([speed)
  // Start the motor. `isOn` property set to |true|
  // Takes an optional parameter `speed` [0-255]
  // to define the motor speed if a PWM Pin is
  // used to connect the motor.
  motor.start();

  // stop()
  // Stop the motor. `isOn` property set to |false|
