I have a power meter that blinks via an IR LED. I also have an IR receiver (from a microsoft media center remote system, the 3.5mm jack type). I've been trying to use the receiver with the IR signal, but do not know exactly which type I have (two leads). During trial and error, I found that once it was powered in reverse, it lit up with a visible red light. Does this mean I have a LED and how do I read signals from this?
