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 ...

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 ...

The ATTINY45 provides 20 millisecond pulses on either the right turn output or the left turn output. The ATTINY84 provides 20 millisecond pulses on either the right turn output or the left turn output ...

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 ...

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 ...

EBE Sensors+Motion has revised its manual handwheel rotary encoder, designed for precise adjustment of machines. Inside the encoder, called HR100, the 100 detent ‘clicks’ are created by magnetic ...

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 ...
