Fun little project for a simple scrolling input method using a potentiometer and a few buttons. Given that the Arduino Uno R3 I am using cannot communicate with the PC as an HID device unless the user ...

Last time, I told you how to get started with the “Black Pill” STM32F411 board using the Mbed OS. The example program, admittedly, didn’t use many of the features of the OS, unless you count what the ...

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 ...

One fun and cool thing for ardent audio folks to do is switch the volume of an audio amplifier between levels on a digital panel. Here’s a simple project to help you understand the technology behind ...

This project demonstrates how to control a servo motor using a potentiometer connected to an ESP8266 development board (such as NodeMCU or Wemos D1 Mini). As the potentiometer is turned, the servo ...
