Ok, I see you are struggling, so i made a video. If you made the circuit as per the first video, here is part 2. It actually does work!
Thank you for your time. Yes it works like on the video you sent me.
* Now if I upload to arduino the AutoSteer INO i must check with the same way if the relays work and make the whole circuit (motor,swm,etc)?
I dont have understand what i must do to make the AutoSteer project.
