6 Pcs KY040 Rotary Encoder with Knob Cap 360° Rotation and Reset Button for Arduino

KY040 Rotary Encoder Key specifications Working voltage: 5V Pulses per revolution: 20 360 degree rotary encoder with continuous rotation and bidirectional pulse counting Integrated push button to reset the count to zero Why you need this encoder Accurate incremental feedback: Outputs a defined number of pulses per rotation, so you can track position, speed, or steps precisely in control and interface applications. Direction sensing: Detects forward and reverse rotation, simplifying directionaware control of motors and systems. Easy reset: Builtin push button returns the encoder to its initial state and restarts counting from zero, useful for calibration and user controls. 5V logic compatibility: Operates at a standard 5V supply for direct use with common microcontroller projects and control boards. What makes it stand out Simple, reliable operation for incremental control tasks without limiting the number of rotations Minimal wiring and straightforward integration into control circuits Versatile for a variety of applications where rotational input and pulse counting are required Function, compatibility, and performance Function: Provides incremental pulses on rotation and a momentary pushbutton reset; suitable for counting rotations and detecting rotation direction Compatibility: Designed for 5V logic systems and microcontrollerbased projects Performance: 20 pulses per full turn deliver a predictable resolution for position and step control; continuous rotation capability supports longrunning or unlimited rotation use cases Typical applications User interface control: Menu selection, parameter tuning, and encoder knobs for embedded devices and DIY electronics Motor control: Position or speed input for stepper and servo motor systems where incremental feedback improves control precision Signal adjustment: Digital potentiometer or gain control systems where precise, incremental adjustments are required Notes for use Integrate with your controller input routines to count pulses and determine direction; implement software debouncing as needed Ensure a stable 5V supply for reliable operation The KY040 rotary encoder provides a compact, direct solution for precise incremental input and control in electronic and robotics projects, offering straightforward integration and dependable pulsebased feedback.
