I have had a lot of fun with an IR project from the playground, which can be found at the following link: http://arduino.cc/playground/Code/InfraredReceivers
Thanks to Walter Anderson for all the heavy lifting on this project.
I have spent some time and effort modifying the program and would like to post my modified version for the benefit of anyone who might be interested. What I am wondering is how I can do this, what are the generally accepted conventions and protocols for doing so, and how do I technically go about getting it into the playground. Can anyone help me out with advice on that?
