Yaluke has created a Raspberry Pi Pico-powered protractor that can be used to calculate rotation data for simulating steering wheels when driving.

He’s converted a mouse into a tuning dial. The scroll wheel on a mouse is nothing more than a rotary encoder, and can easily be used as a sort of tuning knob. Replacing it with a better encoder ...

An Arduino Due forms the heart of the project, controlling a TEA5767 module, an SH1106 128×64 pixel OLED display and a rotary encoder. The sound signal is passed through an LM4811 headphone ...

According to Yaluke, the Pico relies on a rotary encoder module to determine the rotation data. This information is fed to the Pico using a GPIO connection. The precision of the measurement can be ...
