I've attached a program that may work for you -- I wrote it for someone else and haven't had the time to test it myself. You'll also have to change the IR Led connections as this program uses one pin for modulation and another pin for on/off control. ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=1&m=196791#m196793 Need assistance?
