The Rotary Encoder Module is a versatile input device used to detect rotational movement and direction. Unlike traditional potentiometers, it provides digital signals that indicate rotation steps and direction, making it ideal for precise control applications.

This module typically includes a rotary encoder with an integrated push-button, allowing both rotation and click input. It outputs digital signals (CLK and DT) that can be read by microcontrollers such as Arduino, AVR, and PIC to determine position changes.

Widely used in user interface controls, menu navigation, volume control systems, and industrial applications, this module is a reliable and easy-to-use solution for interactive projects.

Its compact design and simple interfacing make it suitable for both beginners and professionals working on embedded and automation systems.
