Hi Guys I am working on this project where I need to detect a IR signal from a transmitter which will be transmitting at a given frequency ( not decided yet). I will have three to four different detectors and I need to see which one is receiving the stronger signal. In short I need to see if I am receiving the frequency and also see the level of signal being received. how can I do that ? best regards Luis -- http://www.piclist.com hint: The PICList is archived three different ways.
