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 ...

There are many forms of human interface device beyond the ubiquitous keyboard and mouse, but when it comes to fine-tuning a linear setting such as a volume control there’s nothing quite like a knob.

In a test circuit built with C3 = 1nF and R6 = 100kO (giving dt ˜ 100µs), the actual step size was measured as 59.7mV. Figure 3a Output waveform created by CW and CCW encoder rotation (4s/div., 2V/div ...

As wonderful as mechanical keyboards are, most of the pre-fab and group buy models out there have zero media controls. If you want rotary encoders and OLED screens to show what function layer you&#… ...

The PMX-1R is a full function wired remote controller with a 2.7" full-color display for PMX source units. Multi Zone Control, Front Panel Sub Control, Waterproof Rotary Encoder Volume Control, Front ...

The rotary encoders are crucial components of many precision control systems and using gray codes in such systems helps ensure accurate positional data. Hence, it is imperative to efficiently convert ...

The same chip-scale encoder package can be used with a linear or rotary reflective scale, with a built-in index mark, which increases production volume and helps drive down costs (in OEM quantities, ...
