<3 robots!

Arduino is your key to the robot world behind the scientists doors

Meet THE ARDUINO

A MICROCONTROLLER FOR EVERYONE

Arduino

• A tool for making computers control & sense more of the physical world
• Arduino projects can be stand-alone
• Or they can be communicate with software running on your computer
• Inexpensive - starts around 25 Euro
• Cross-platform - works on *nix & Win
• Open source - even the hardware layout
• 3rd Party Extensions - displays, network adapters, 3G adapters...

Cool dude, but we are at a JavaScript Conference...

A bit of history

Node serialport

• Born Sep 07, 2010
• Bidiricetional communication via the USB Port over the SP protocol
• Node.js was able to connect to real world!
• Arduino can be controlled via the SP protocol. Hmmm......

Johnny-five

• Connect to arduino from node
• Super slick api

• board = new five.Board();

• led = new five.Led({pin: 13});

• led.on();

• Thx @rwaldron (and all the contributors)

Isn´t that difficult, you know hardware & things?!

No!

DEMO TIME

Leds (Scheme)

Leds (Code)

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: 13
  });

  // "on" turns the led _on_
  led.on();

});

Sensors (Scheme)

Sensors (Code)

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

board = new five.Board();

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

  // Create a new `photoresistor` hardware instance.
  photoresistor = new five.Sensor({
    pin: "A2",
    freq: 250
  });

  // "read" get the current reading from the photoresistor
  photoresistor.on("change", function(err, value) {
    console.log(value); // or io.sockets.emit('pr', value);
  });
});
