..as I understand it a modulated IR reciver is a photodiode and a IC that does some comparison or encoding..
anyone know if this IC function can be replaced by another IC, and then be connected to a larger number of photodiodes? I want to use a larger number of cheaper IRphotodiodes instead of the more expensive IR modules for object detection on my robot..
datahsheet on a typical reciver.
