This CircuitPython project adds a dedicated volume control to a PC using an Adafruit QT Py RP2040 and a Stemma QT Rotary Encoder. The rotary encoder adjusts the system volume, while pressing its ...

This project features an under-the-desk-style volume mixer with six rotary encoders for controlling individual audio channels on your PC, a display for visual feedback, and an air quality sensor that ...

Rotary encoders are electromechanical transducers that convert angular displacement into corresponding electrical signals interpretable by digital systems. This article specifically focuses on panel ...

Experimenting with an HF oscillator, I needed to control the varactor diode voltage in precise increments over a 2V-10V range. A buffered potentiometer was the obvious choice, and connecting two pots ...

Rotary encoders sense changes in the position of a rotating shaft, then generate signals that send speed, direction, and position information to a receiving device such as a counter, drive, or ...

[Mitxela]’s repair of a Roland JV-1080 (a rack-mounted 90s-era synthesizer) sounds simple: replace a broken rotary encoder on the front panel. It turned out to be anything but simple, since the part ...

Precisely tracking speed, acceleration, and position of a motor's rotor is an essential requirement for many motor control applications found in everyday equipment such as fax machines, elevators, and ...
