hey guys I've been reading around on here for what seems like days and can't seem to find an answer. heres what i want to try and accomplish. i just want to be able to send the CEC command to turn on my tv. it sounds simple but everything i read on here is very in depth and detailed and does 1000000 things, for now i just need to do this one thing. is it possible? is it as detailed as I've been reading on here? can anyone give me some leg work to go off of? thanks in advance i appreciate it.
You should get an IR receiver module, and use it with the IRremote library to find out which protocol is used by your control, and which code is sent for the key.
Then add an IR LED and make it send the same code, again using the IRremote library.
You may want to use 2 Arduinos for testing, one as the sender and one as a receiver, so that you can verify that your IR sender works and sends what you want.
