Record incoming IR pulses with an IR Receiver on an Arduino
/* Raw IR decoder sketch!
This sketch/program uses the Arduno and a PNA4602 to
decode IR received. This can be used to make a IR receiver
(by looking for a particular code)
or transmitter (by pulsing an IR LED at ~38KHz for the
durations detected
Code is public domain, check out www.ladyada.net and adafruit.com
for more tutorials!
