Hello all, I have been struggling with my circuit for over a week. I am trying to build a voltage tracker with a feedback loop. I want to get analog input reading using a potentiometer and I want to output exactly the same reading, 1v=1v,2v=2v,3v=3v,4v=4v,5v=5v. I am outputing pwm value and using RC…
