| Hello Handyboarders, I hve a few questions regarding IR demodulation. Fred's book shows both the GP1US2 and the IS1U60 IR demodulators but only shows how to hook up the GP1US2. I would assume that this is because they would both be wired the same (...) (23 years ago, 28-Sep-01, to lugnet.robotics.handyboard)
