/* DVD IR Synchronizer for Philips DVP3142/12
 * Developed for Art Installation "Thor"
 * Code written by Joe Foley <foley@ru.is>
 * on 2013-09-08
 * !!!WARNING: THIS CODE DOES NOT WORK!!!
 *
 * Requires libraries:
 *  Arduino-IRremote https://github.com/shirriff/Arduino-IRremote
 *   Instructions http://www.righto.com/2009/08/multi-protocol-infrared-remote-library.html
 *
 * IR Remote codes 
 * http://lirc.sourceforge.net/remotes/philips/DVP-5982
 *
 * 
 *  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)
