1. Hardware Development for JavaScript Developers Tarık Keleştemur" • github/tkelestemur! • twitter/tarikkelestemur! • kelestemur.com
2. About Me • Electronics Engineering Student at TOBB ETU #3 • Co-Founder at GMTLabs.com • Working on embedded sys. and robotics ! ! more info : kelestemur.com
3. Agenda • A Brief History of Electronic Prototyping • It's all about C. How JS involved ? - Main Concept • JS Hardware Frameworks • Demonstration ! ! !
4. Hardware Prototyping • Texas Instruments • IBM • Atmel • Microchip ! ! ! ! !
5. Electronic for Everyone : Arduino • 16MHz micro-controller • Easy programming with Wiring • Open Source! • Great for driving motors,
 reading sensors BUILDING ROBOTS! ! !
6. Electronic for Everyone : Other ! !
7. The Problem • Micro-controllers are running at low speeds. • They are not capable of handling high-level jobs
 such as math, media processing • They are programmed with C language. • C does not have awesome JavaScript libraries. !
8. The Solution • Using JavaScript as controller software of these hardwares. ! ! ! • Serial communication is made by a node package called serialport • Special Firmware let you control your hardware over serial comminaciton with JavaScript. We don't write any C code :) NODEJS + 
 HW Framework uController +
 Special Firmware Serial Comm
9. Hardware Frameworks ! ! ! ! ! Johnny-Five Cylon.JS
10. Johnny-Five • Compitable with almost every electronic board :
 Beagle Bone, Intel Galileo,Pinoccio,Raspberry Pi, Spark Core, Arduino of course. • Uses node-serialport package by Chris Williams • Has a large community : NodeBots, NodeCopter, NodeRocket !
11. Johnny-Five • Accelerometer, Button, Compass, Led, Joystick, Motor, (Ultrasonic) Ping, Proximity IR, Range IR, Sensor, Servo, Sonar • http://jsfiddle.net/rwaldron/XMsGQ/show/light/
12. Johnny-Five Examples var five = require("johnny-five"); five.Board().on("ready", function() { (new five.Led(13)).strobe(100); }); • It says arduino to blink the led atteched to pin13 in every 100 ms over serial port.
13. var five = require("johnny-five"); five.Board().on("ready", function() { var claw, joystick; // Claw servo controller claw = new five.Servo(9); // Joystick controller joystick = new five.Joystick({ // x, y (vertical, horizontal) pins: [ "A0", "A1" ] }); ! // Center the claw servo to match the joystick deadzone. claw.center(); ! // When the joystick axis are moved... joystick.on("axismove", function() { // Open & close the claw by setting degrees according // to Y position value of joystick. claw.move( Math.ceil(180 * this.fixed.y) ); }); }); https://dl.dropboxusercontent.com/u/3531958/nodeconf/joystick-claw.mp4
14. Demos • Arduino : Blinking LED, Servo, Reading Sensor Data • Spark Core : Internet of Things Example ! !
