arduino and raspberry pi controlled rc car/ truck PWM most controllers will work just edit button values make sure all parameters are correct specifically to you if you get error(s) min to max throttle is 0-180 min to max steering is rc vehicle dependent i used a ps3 controller via bluetooth for button control
i used xpadneo driver for xbox one s controller on rapsbian axis control, but most other controllers will work. just be sure to assign the correct values in the code. for calibrating castle creations esc's, you must turn the esc on while already giving full throttle, after beeps do full reverse, after beeps do neutral. if you want to also use buttons for your code, refer to https://pypi.org/project/inputs/. when you install nanpy firmware make sure you enable use servo.
