- loop() updates current steering angle from the car, and desired angle from Openpilot.
- Based on the difference it calculates how many steps to move to achieve the desired angle and requests to move there.
- It continues to update at 200hz as both current angle and desired angle changes.
- Also takes advantage of the enable pin on the A4988 to disable the stepper when not engaged.
ToDo:
-Update README with more details
-Improve comments in Arduino code
-Draw circuit details
-Make OLDCAR Panda
