JavaScript and Internet Controlled Electronics
This document discusses using JavaScript and the internet to control electronics. It introduces several hardware platforms like Arduino and Raspberry Pi that allow connecting electronics to computers. It then explains how JavaScript and Node.js can be used with these platforms through libraries like Johnny-Five and Firmata to control devices from code. Examples are given of using JavaScript to control an LED light and servo motor connected to an Arduino microcontroller board.

Editor's Notes
- #5 Internet Controller Hardware – Arduino Yun, etc.Extending to other languages, Tessel = JavaScript, Node.js through Johnny 5
- #9 Arduino Yun
- #10 Yun feature sets (temboo / wifi / etc)Based on the Leonardo boardPython 2.7 included with OpenWRT Linux distribution called Linino on the board
- #11 Program an arduino without writing any code.Sketch Builder (https://temboo.com/library/Library/devices/)
- #12 Picking the right version of the arduino softwarehttp://arduino.cc/en/main/software
- #13 Picking the right version of the arduino softwarehttp://arduino.cc/en/main/software
- #14 Picking the right version of the arduino softwarehttp://arduino.cc/en/main/software
- #17 The modularity and extensibility of the Devices sets them apart from just usingThe hardware components of a phone, etc
- #18 Alternate framework: Noduino (http://semu.github.io/noduino/) – accessing arduino from web applications (HTML5 / JS / Node)
- #19 How Johnny 5 works – standard firmata uploaded to the microcontroller, then Node.js script controlled.
- #20 http://arduino.cc/en/reference/firmata
- #21 Upload the firmata program to the board
- #22 Crap that was hard…
- #25 servo.min(); //set to min degrees (default 0)servo.max(); //set to max degrees (default 180)servo.center(); //center servo to 90 degrees
- #26 Alternate framework: Noduino (http://semu.github.io/noduino/) – accessing arduino from web applications (HTML5 / JS / Node)Download NoduinoUploadDuino to board (the communications bridge)
