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 ...

On my Raspberry Pi machine I wanted a hardware volume knob. The speakers I got for my cabinet are great, but don't have their own hardware volume knob. So with a bunch of googling and trial and error, ...

A rotary encoder is a type of electromechanical position sensor that can be used to identify the angular position of the rotary shaft. This type of sensor or module generates an electrical signal ...

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 ...

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 ATTINY45 provides 20 millisecond pulses on either the right turn output or the left turn output.

Touch screen head units are pretty much the norm these days. Many compromise with annoying on-screen volume controls or tiny buttons. If you find yourself with such a unit, you might like to hack in a ...

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 ...

If you buy expensive computer speakers, they often have a volume knob you can mount somewhere on your desk so you aren’t dependent on the onboard volume control. [Kris S] decided to build his own ...
