Anyone got any experience with infrared remote control? I need a circuit which will enable me to remote control 4 functions on a "robot". For my purposes, a "function" is being able to switch a DC motor one way, stop it or switch it the other way. I need to do this with four motors. Other people might define this as 12 "functions" !!!
I have seen IR tx/rx units which have 5 "bits" of control. Using a binary system, this ought to give 32 "functions", but I am not sure how this could be implemented.
Anyone able to give me any clues?
