The Rotary Encoder Module is a versatile input device used to detect rotational movement, direction, and position in electronic systems and embedded applications. Unlike traditional potentiometers, rotary encoders provide continuous rotation with digital pulse outputs, making them ideal for precise control and navigation tasks.
This module typically features an incremental rotary encoder with integrated push-button functionality, allowing both rotational input and button selection in a compact design. It can detect clockwise and counterclockwise movement and generate corresponding digital signals for microcontrollers.
