I have found this project (https://create.arduino.cc/projecthub/richardosgood/clone-infrared-signals-with-arduino-3a3cb2?f=1) about cloning a remote control. I set up the Arduino and managed to copy the ON command of my LG remote control, the problem is that when I try to play the signal it doesn't work. I think that it could be a frequency error but I wasn't able to find anywhere the correct frequency for my tv (model 32ls5600). Does anyone know how to fix this problem ? I'm currently sending the signal at 38khz. Thanks everybody!
