IR remote

Hi I'm having troubles replicating the IR transmission of my AC remote. I'm using two arduinos, one to send the command, and the other to learn the command and to verify the send. I've successfully learned one of the transmission code, and verified when I'm transmitting it I get the same results. Even though, my AC fails to accept it, no matter if I use raw, or build in functions.. Any ideas?

AC remotes use their own protocols and can be 100s of bits long.

Search in the box at top of page. IR remotes are a common subject.


Try searching online for AC remotes.

Unlike tellys etc AC remotes do not just send one command they often store every setting and send the lot every time you press the button.
