Lights

Outputs

Relays

A physical switch we can control through code

How does a relay work?

Ideas for how to use relays...

Board: Arduino UNO

Microcontroller

Like frameworks

Shields

Like our libraries/modules/packages for hardware

JavaScript Framework

But first, why JavaScript?

Rick Waldron, author of Johnny-Five

Also...

Lots of different libraries

Browser as an input and output

How?

The inspiration


$("livingroom").bind("motion", function() {
  $(this).find("lights").brightness("75%").dimAfter("120s");
});

Browser

Inputs

Endless possibilities!

Let's dive into the code...

Let's code one right now


var five = require("johnny-five"),
  board, led;

board = new five.Board();

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

  // Create a standard `led` hardware instance
  led = new five.Led({
    pin: 12
  });

  // "strobe" strobes the light
  led.strobe();

});
