I think i found this on your Post: https://dronebotworkshop.com/radio-control-arduino-car/ where you use this sketch with the arduino mega pin 19 (serial rx 1) im trying to read the ibus data with an arduino uno. I cannont work out how to do this is there a difference between the rx pins on the uno and mega?
