All motion detection components now live under the same roof. These components detect motion--typically by sensing changes in infrared or ultrasonic field--and provide a boolean state. Johnny-Five now handles all motion detection components consistently, emitting motionstart and motionend events, in addition to other standard events such as change and data. Components that require a calibration delay also emit a calibrated event.

Check the API docs for a list of supported components, and how to use them.

var five = require("johnny-five");
var board = new five.Board();

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

  var motion = new five.Motion(7);

  motion.on("calibrated", function() {
    console.log("calibrated");
  });

  motion.on("motionstart", function() {
    console.log("motionstart");
  });

  motion.on("motionend", function() {
    console.log("motionend");
  });
});

This change will not affect existing code, but IR.Motion, and Pir have been deprecated and will be removed when Johnny-Five reaches 1.0.

Please report any issues here.
