]Hi all, the transistor is correctly joint. (from datasheet). I experimented for a while and got it to work :) I have no ideas why but the AC works with this sending solution see below code. the part off code was taken from here->https://www.analysir.com/blog/2016/04/11/sending-long-ac-signals-flash...

Hello, I have YUN board. The IR LED is connected to the arduino PIN13 but not directly. pin13 connects to the NPN transistor which trigers and enable the IR LED. I looked at IR led form phone camera and I can see the light flashes. I will try to put the code to another arduino which controls mitsubi...

Hello,
today I finally got to the AC, and nothing happened.
I put the 9nnn value back before test.
What else could be wrong?
The board works, tested with the samsung tv on/off signal.

Thanks,
will put the first value back and try again.

Hello everyone, I am trying to turn on air conditioner from Arduino yun board. the bord is running fine I tested it by turning on my TV.
