This is a 360-degree rotary encoder module based and designed on the Keyes KY-040 rotary encoder, which is a rotary input device (as in knob) that provides an indication of how much the knob has been rotated AND what direction it is rotating in.

It is quite suitable for applications such as a volume knob and varying lighting voltage. The rotary encoder module is also easy to use in prototyping applications such as automotive electronics, multimedia speakers, instrumentation, smart home, digital potentiometers, stepper, and servo motor control and more.
