I don't know the technical term for this phenomenon. It goes like this:
An IR decoder is connected to V, ground and it's signal pin a LED. Also, an AVR micro is connected to V, ground, and one of it's pins to another LED. The micro is programed to oscillate that pin at 38 KHz, which is the carrier frequency the the IR decoder is designed to decode.
The phenomenon I get is that the IR decoder always indicates a signal.
I think my circuit lacks a capacitor somewhere. I've put capacitors everywhere but it didn't help. Sometimes the IR decoder calms down and behaves but this is rare.
What's going on here?
