I poke in my Arduino folders, but I didn't the actual C program created by the Arduino IDE.
Something I do wrong.
My information is based on the older versions of the IDE. Check out this (http://smileymicros.com/blog/2011/02/10/where-is-the-arduino-hex-file/) and see if it helps. He is looking for the 'hex' file but the 'cpp' file should be nearby. Don't forget that you have to look for the file before you close the IDE.
