Description:
The KY-040 Rotary Encoder Module is a versatile input device that converts rotational motion into digital signals, enabling precise control in various electronic applications. Unlike traditional potentiometers, this incremental encoder provides continuous 360-degree rotation without mechanical limits, making it ideal for tasks requiring precise position sensing and user input. The module features a built-in push-button switch, adding an extra layer of functionality for menu selection or parameter adjustments.
Designed for seamless integration with microcontroller platforms such as Arduino and Raspberry Pi, the KY-040 outputs two-phase quadrature signals (CLK and DT) that detect the direction and speed of rotation. Its straightforward pin configuration and compact design make it a popular choice for projects involving motor control, volume adjustments, and user interface navigation.
