/* Code written by Joe Foley <foley@ru.is> on 2014-01-14
 *
 * Requires libraries:
 *  Arduino-IRremote https://github.com/shirriff/Arduino-IRremote
 *  Streaming http://arduiniana.org/libraries/streaming/
 * More codes at http://www.lirc.org/
 * This uses remote Sony RMT-B122P
 * 
 *  The IRremote library uses Pin 3 for the Anode (longer pin)
 *  We have made a ground pin on Pin 4 for the Cathode (shorter pin)
 *
