Arduino sendSamsung method on IRemote library

Using Arduino LEDs and Multiplexing
#1

Hello!

It's been a long time I don't work with arduino. Just found my old arduino UNO and a infrared LED. Wanted to turn my Samsung Smart TV on, but couldn't find helpful information on the web.

I've seen that they added the sendSamsung method on the IRemote library, but there isn't even an example of code for the Samsung method, just for the other methods. I just needed the power code, but I can't find it, only raw data.

I don't have the IR receiver, so it's hard for me to discover which code it is. Does anybody know a good place to find a code, or does anybody has a Samsung Smart TV and could measure the code for me?
It would be good to have sample codes for Samsung Smart TVs on the internet.

Thank you :slight_smile:

You can salvage an IR receiver from almost any old home AV equipment like an old VHS VCR.

Tru the following, recorded a few signals from a Samsung just now.

You could also use the HEX values at the top, instead of the send RAW
