I need to make a motorized volume control that works with a remote. I wish they came with stepper motors but they do not appear to. I could make one but wanted to see how involved it would be to control the available dc motor types. I was thinking of dividing the entire travel into some increment. Then have it so each time you pressed the remote button it would move one increment. Hold the button for a second and have it start ticking them off in a quick and controllable manner. What would be the easiest way to achieve this? Would the available pid library be a good solution? There is examples of people doing this but all the ones I can find never circled back and say what they did exactly just that "it worked".
No, you don't need PID or any other library other than maybe the IR library
