- Package includes 5 pieces of KY-040 5-pin rotary encoder modules, designed for 360-degree rotation. Each module operates at 5V and can count up to 20 pulses per circuit. - Optimize your projects with a rotary encoder that provides precise counting in both clockwise and counterclockwise directions. Unlike rotary potentiometers, this encoder offers unlimited rotation, making it ideal for continuous feedback applications. - The D shaft on each module serves as both a rotating knob and a clickable button. This dual functionality allows for versatile control options in your designs. - Easily reset the encoder to its initial state by clicking the D shaft, enabling you to start counting from zero with just a simple action. - Applications include: 1. Robotics: Use multiple encoders for precise movement control in robotic arms or wheels. 2. Audio Equipment: Implement in volume controls or equalizers for accurate adjustments. 3. User Interfaces: Create intuitive user interfaces in various electronic devices where precise input is needed. This KY-040 rotary encoder module is compatible with a wide range of microcontrollers, ensuring seamless integration into your projects. Its compact size and reliable performance make it an essential component for hobbyists and professionals alike.
