I'm trying to use 2 attiny85, one with an IR transmitter and one with an IR receiver (2 pins). I can't figure out how to use the attiny85 with the receiver. Help would be appreciated! If it is not possible to do it with a 2 pin IR receiver, advice for a 3 pin one would be fine too. Basically, I'm trying to let the attiny85 with the receiver do something when it senses the one with the transmitter is on. Thank you.
Here are a few Ir receiver/transmitter projects using Attiny85's and Arduino's that you can read through for some info:
