KY-040 Rotary Encoder Module Brick Sensor

Description

The KY-040 Rotary Encoder Module Brick Sensor is a small device used to detect rotational movement and direction. It consists of a rotary encoder and a switch, which can provide both positional and tactile feedback.

The rotary encoder uses a shaft that rotates and has a number of evenly spaced notches or detents. As the shaft rotates, the encoder sends a series of pulses that can be used to track the position of the shaft. The KY-040 rotary encoder can provide up to 20 pulses per revolution, which makes it very precise.

In addition to tracking position, the KY-040 rotary encoder module also has a built-in switch that can be pressed to provide tactile feedback. This switch is useful for applications where the rotary encoder is used to select options or navigate menus.

The KY-040 rotary encoder module is easy to use and can be connected to microcontrollers or other devices using three pins: ground, power, and signal. The signal pin outputs the pulses generated by the rotary encoder, which can be read by a microcontroller to track the position of the shaft.
