A servomechanism is technically any automatic device that can correct its own position based on negative feedback. Negative feedback is the process by which electrical signals are fed back in a manner that ultimately reduces further fluctuations. Servo motors can rotate or push components with amazing accuracy using this method. Servos are very widely used in a vast array of electronics. Volume knobs, gas pedals, even…
