Potentiometers and encoders may look similar, but they work completely differently. A potentiometer is a variable resistor – turning it changes resistance. An encoder contains two microswitches with staggered timing, producing digital open/close signals – perfect for digital circuits and replacing buttons. In this video, I tear down an encoder to reveal its internal structure: a gear‑shaped contact, two sets of brushes, and the clicking mechanism. See exactly how it works – clear, quick, and straight to the point. Great for beginners and electronics enthusiasts.
