This project uses a rotary encoder and an Arduino to create a basic cross-platform hardware volume control. The hardware setup is as easy as connecting the clock, direction, and button pins of the ...

I was messing around with Phil Schatzmann's library and how to use a Rotary Encoder, and then I accidentally created a Bluetooth device using a Rotary Encoder to control the volume. The device's ...

One of the redeeming qualities of many modern cheap keyboards is the built-in volume control buttons. But this is Hackaday, and many of us (and you) have Model Ms or newfangled mechanical keyboards ...

We’ve all been there. You’re manning the battle station, deep in the sim-racing or some other n00b-pwning zone and suddenly some loudmouth blows out your eardrums over Discord. It’s insulting to have ...

This design idea details how a standard volume control can be replaced by its solid-state equivalent. Digital potentiometers are often advertised as replacements for rotary volume controls. To ...

LILYGO TTGO T-Encoder, a round-shaped ESP32 board with a built-in rotary encoder, has gotten a shield with a 2-key keypad based on WCH CH552 8-bit microcontroller. Launched several months ago, the ...

The other day we had a big problem. The Saddle feeder's speed control was done by a hydraulic device which consists of a wheel having a complete 360 degree rotation representing from zero speed to ...

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 ...

Abstract: The paper proposed the design and implementation of generation and control of a PWM waveform that has a changing duty cycle using rotary encoder. The model was developed and executed using ...
