SSIRR v.10
a Simple Serial IR Receiver

Based on an example program from Shirriff's blog. This adds the 
necessary output info needed to use Shiriff's IR library to send
signals.
This version of this program is meant to be as simple as possible
for the task at hand. Tested and working with Mega2560. 

File edited and re-released by xclusive585@gmail.com

Point a remote at the receiver, push a button. Info can be viewed
from Arduino serial monitor. Record the received info and the button 
it corrosponds with. 
Sometimes the receiver is succeptable to interference, it is very
easy to notice and dismiss the false signals.

Enjoy
