My previous blog Encoders Know All the Angles introduced encoders that provide information about rotary positions. A diagram illustrated the phase relationship of signals from an incremental encoder.

Rotary encoders are popular input devices that can be used to measure and control the position and rotation of a shaft. The Raspberry Pi Pico, with its GPIO pins and capabilities, provides an ...

AS5035, an 8-bit incremental magnetic rotary encoder for cost-sensitive industrial and automotive applications, is suited for use in human-machine interface applications, such as front panel switches, ...

Using this interface circuit you can use an old HDD drive as a rotary encoder and react to increment/decrement events very easily. This is based on and inspired by Franck Fleureys project.
