So using I2C with its requirement of just 2 GPIOs is already a big plus for the Rotary Encoder discussed here. In addition, the PCB comes with two additional GPIOs that you can freely use and control ...

This sketch reads the rotary encoder module and displays the value along with a slider on the built-in screen using the TFT_eWidget library. The counter value and slider position are updated in ...

This paper introduces a low-power spintronic rotary encoder capable of 8-bit analog-to-digital conversion. The proposed encoder leverages Spin-Hall Effect-driven Domain Wall Motion (SHE-DWM) within a ...

He ended up exploring hard drive motors as encoders, and while the results aren’t exactly high resolution, he may be onto something. Starting with a teardown of some old HDDs — save those magnets!

Elma Electronic Inc. now offers a miniature rotary encoder that includes an illuminated 8+1 joystick, enabling seamless, accurate control using just one finger.
