Code for IR Arduino Receiver – Electronics Freak

/*
 * IRremote: IRreceiveDemo - demonstrates receiving IR codes with IRrecv
 * An IR detector/demodulator must be connected to the input RECV_PIN.
 * Initially coded 2009 Ken Shirriff http://www.righto.com/
 * Roee Bloch Improved for Arduino UNO with LCD (LCD Keypad shield)
 * connect IR Receiver to Pin 11 
 * IR connection from Front    OUT - GND - VCC
