Description KY-040 Rotary Encoder Module is an electronic component used to detect the rotational movement and direction of a shaft. It consists of a rotating disk with a set of contacts that generate pulses as the encoder is turned. The module has three main pins: CLK (Clock), DT (Data), and SW (Switch), along with a push-button feature when pressed. It is commonly used in projects for input control, such as volume knobs, menu navigation, or adjusting settings in microcontroller-based systems like Arduino. This module is known for its accuracy, durability, and ease of integration into various electronics projects.
