Hi!
I’ve taken on the project of getting an rc car from the thrift store and replacing the motherboard with an Arduino, a dual channel h bridge, and a hobby transmitter and receiver but the steering is controlled with a dc motor with gears. There isn’t even a potentiometer. I don’t understand how they made this work originally. How should I go about programming I want the wheels to center when the stick does. I have another car I’m doing the same thing to but it has a potentiometer hooked up to the axel of a gear. How would I go about programming that? I tried before with a bunch of if statements and like targetValue and currentValue and tried to make them be the same and no matter what I did it was too sensitive and kept wobbling back and forth. I’m sure there’s a better way I just haven’t been able to focus much more on this and I’d like some help.
Thank you for helping if you decide to. I really appreciate the sharing of knowledge and it’ll help me learn.
