I would like to read the "Rotary Encoder with LED (Red) with Knob Set" available at Akizuki Denshi Tsusho using an ESP32. In two previous articles, I implemented this using polling and was able to ...

Arduino is being acquired by Qualcomm subject to regulatory approval for an undisclosed sum. Qualcomm Arduino introduces a new UNO form factor board, the Arduino UNO Q, which features both a STM32 MCU ...

Paul and David Bradt’s Ardiono Projects offers multiple ways to use Arduino and Raspberry Pi microcontrollers for your model railroading projects. Buy the book here. Code for Button/Blink Test (SN095) ...

This library implements non-blocking functions to detect encoder rotation actions. The library can handle multiple encoders. For rotary encoders with an integrated push-button switch, this library can ...

We love Arduino here at Hackaday; they’ve probably done more to make embedded programming accessible to more people than anything else in the history of the field. One thing the Arduino ecosystem is ...

Customization is often touted as the key advantage PCs have over consoles for gaming. Personalizing the user experience down to how your peripherals interact with the computer can deliver significant ...
