• Stuff we don't need
• A recipe for IoT hacking
• Silly demos

No low level code

No complicated circuits

Firebase Platform

Firebase Realtime Database

Realtime is where your bus is

Realtime is collaborative drawing

Realtime game state

Some JavaScript code

var ref = new Firebase("https://io.firebaseio-demo.com/");

ref.set("Hello, Developers!");

ref.on("value", function (snapshot) {
  var data = snapshot.val();
  console.log(data);
});

Put it all together

var five = require('johnny-five');
var Firebase = require("firebase");
var board = new five.Board();
var firebaseRef = new Firebase("https://firebutton.firebaseio-demo.com/button");

board.on("ready", function () {
  var button = new five.Button(8);
  var led = new five.Led(13);
  button.on("up", function () { firebaseRef.set(false); });
  button.on("down", function () { firebaseRef.set(true); });

  firebaseRef.on("value", function (snapshot) {
    var buttonValue = snapshot.val();
    if (buttonValue) {
      led.on();
      setTimeout(function() { led.off(); }, 2500); }
});});
