Thank you for this code! It didn't fully work for me, maybe because i'm using Manjaro linux. It says that "Serial conection started, waiting for instructions..." but when I try to run "echo "ON">/dev/ttyUSB0" or "sudo echo "ON">/dev/ttyUSB0" it says "zsh: permission denied: /dev/ttyUSB0". So u have any tips?
