RC5Decode.ino

/*
 *  Wiring notes:
 *  
 *  Using IR sensor like this:
 *    http://www.adafruit.com/products/157
 *  wired as follows:
 *   pin1 - arduino pin 7 
 *   pin2 - ground
 *   pin3 - 5V
 *  
 *  This code will display address, command and toggle for decoded sequences.
 *  Pressing the power button twice gives this result:
 *     a:0 c:12 t:0  <- first press, a:0 => TV1, c:12 => Standby command.
 *     a:0 c:12 t:0
 *     a:0 c:12 t:0
 *     a:0 c:12 t:1  <- second press, toggle changes
 *     a:0 c:12 t:1
 *
