KY-040 Rotary Encoder Module
Overview:
The KY-040 Rotary Encoder Module is a popular sensor used to detect rotational movement and direction. It operates using incremental encoding, which means it detects changes in position relative to its previous state. The module includes a built-in push-button switch, allowing it to function both as a rotary sensor and as a tactile button. It's widely used in applications where precision control or user interface input is required, and is compatible with Arduino, Raspberry Pi, and other microcontroller platforms.
