The KY-040 Rotary Encoder Module is a versatile input device commonly used with microcontrollers like Arduino. Unlike a potentiometer, it offers continuous rotation without limits, making it ideal for applications requiring incremental adjustments or menu navigation.

Key features:

  • Functionality: Counts output pulses during rotation in both positive and negative directions.
  • Integrated Push Button: Allows for reset to an initial state (e.g., counting from 0) or selection.
  • Operating Voltage: Typically 5V.
  • Pulses per Revolution: Generates 20 pulses per full rotation.
  • Output: Digital signals for CLK, DT, and SW (switch).

Typical applications include:

  • Menu navigation and selection in embedded systems.
  • Volume control or parameter adjustment.
  • Robotics and motor control feedback.
  • DIY electronics projects with Arduino, ESP32, Raspberry Pi.
