Ever wondered what’s actually happening inside that clicky knob on your car stereo? It’s a rotary encoder!.. and it’s one of the most useful little components in electronics. In this video, we crack one open and show you how it works. You’ll learn the key difference between an encoder and a potentiometer, what’s spinning around inside, and the clever offset trick that lets your microcontroller figure out which direction you’re turning the knob and count every single step along the way. #RotaryEncoder #Electronics #Arduino #Microcontroller
