Rotary and magnetic encoders convert rotation into electronic signals, providing position, direction, and speed feedback for robotics, sensing, automation, and embedded projects. They come in incremental forms, which generate a pulse stream you interpret with a microcontroller, and absolute forms, which report a definite position on power up. Variants include mechanical, magnetic, and optical sensing, with options such as a built-in switch, illumination, or rugged sealing for harsher environments.
Interfaces range from breadboard-friendly breakouts to digital serial buses like I2C or SPI, easing integration with common controllers. This mix enables scalable resolution, reliable feedback, and smooth control in motor systems, user interfaces, and automated experiments.
Code: SKU-001109
This is a clever little breakout board for both the RGB and R/G illuminated rotary encoders. On one side it breaks out all of the RGB pins to standard breadboard friendly 0.1" headers. More Details...
