INTERNET OF THINGS A BRIEF INTRODUCTION• A connection of „Things“ (real world objects) with

our beloved InternetsTM

• Enriches all day life experience with Facebook like counters awesome metadata and functionality

• Will hopefully make our lives a lot easier

… FINALLY! :)!34

WHY JAVASCRIPT?• Easy to learn

• Asynchronous

• Popular, great Community

• Awesome because it’s not C. :)

• The last one might depend on who you’re talking to

WHAT CAN BE DONE VIA JS?Build the Frontend (if needed)

Build your Server/Services (i.e. with node.js)

End to end communication (WebRTC)

Hardware Read/Write (node-serialport)

NODUINO

http://semu.github.io/noduino/

var Noduino = new NoduinoObj({debug: true, host: 'http://localhost:8090'}, Connector); Noduino.connect(function(err, board) { if (err) { return console.log(err); } board.withButton({pin: 13}, function(err, Button) { if (err) { return console.log(err); } Button.on('push', function() } console.log('Button pushed'); }); Button.push(); }); });

JOYSTICK CONTROLLED LASER

JOHNNY FIVE

http://jsfiddle.net/rwaldron/YHb7A/show/light/

var five = require("../lib/johnny-five.js"), board = five.Board({ debug: true }); board.on("ready", function() { var range, pan, tilt, joystick; range = [ 0, 170 ]; // Servo to control panning pan = five.Servo({ pin: 9, range: range }); // Servo to control tilt tilt = five.Servo({ pin: 10, range: range }); // Joystick to control pan/tilt // Read Analog 0, 1 // Limit events to every 100ms joystick = five.Joystick({ pins: [ "A0", "A1" ], freq: 100 }); // Center all servos (five.Servos()).center(); joystick.on("axismove", function() { tilt.move( Math.ceil(170 * this.fixed.y) ); pan.move( Math.ceil(170 * this.fixed.x) ); });

OK, THIS WAS QUITE A LOT OF GEEKY GADGET STUFF. BUT HOW

DOES THIS FIT INTO MY BUSINESS MODEL?

BRITISH AIRWAYS

BILLBOARD CAMPAIGN

• Combines IoT with Classic Campaign • Get’s a lot of „buzz“ • Would be easy to implement with JS:

• Flights API • Kinect (node-kinect ) • Some very expensive large screen :)

C&A

FASHION LIKE• Shows 'Likes' on their respective Clothing Racks

• Combines IoT with Classic Campaign • Get’s a lot of „buzz“ • Would be easy to implement with JS:

• Facebook Graph-API • Arduino Mini • Some very cheap small led screens :)

HYPOTHESIS(TOUCH)SCREENS WILL DIE SOON

!50

HYPOTHESISTHE INTERNET AND SENSORS WILL INFILTRATE EVERYTHING

!51

HYPOTHESISTHERE WILL BE NEW, MORE INTUITIVE, MORE PRECISE INPUT AND OUTPUT DEVICES

A FUTURE VISION$("livingroom").bind( "motion", function() {

$(this).find("lights").brightness("75%").dimAfter("120s");

});
