Hi, I found a sketch for the load cell pedal but wish to use a potentiometer for the accelerator can someone help me add a potentiometer to the existing sketch it doesn't need the throttle disabled but I can comment it out. Just finding it really hard to find a sketch that uses both potentiometers and a loadcell I found a forum post on x simulator but doesn't seem to work. I'm a total number and have no clue mostly copied others' code or used chat to make stuff that doesn't work as well as it used to for that kind of thing now. Here's the sketch any help welcome I'm useless
