I have tried to build an IR remote from scratch befoe and had problems distinguishing a signal from ambient light. Does anybody have an idea on how the learning recievers take care of this? I would very much like to create a custom IR reciever board to take care of possible compatibility issues. If we are required to use common IR Com protocals for the device to recognise the data packets, I see a compatibility issue, especially if teams like to use the arrow keys on their remotes. I would like to design a board that uses a start byte, our team number, to rule out any possible "command overlap." Any filtering advice would be greatly appreciated. Thanks.
