I saw some topics about sending/receiving IRs and tried to test it. Through pulseIn(), I successfully received the IRs, but the problem I'm having is to send them back. I don't know anything about how to do it. I'm using an QED234 for IR transmission, and my question is: how do I know what delayMicroseconds() I should use when "sending pulses".
Sorry if I said something wrong, I really need some clarification.
Thanks in advance.
