This is an Arduino project for controlling addressable LED strips (WS2812B) with an ESP32, designed for seamless integration with Home Assistant via MQTT. It provides a flexible effect system that ...

Description: Using an Arduino or a micro controller, we can generate cool-looking patterns with an led strip containing addressable LEDs. In this case, I'm using an Arduino uno (clone board) and a ...

Brushless motors are fascinating devices that come in all sorts of shapes and sizes, but you’ve probably never seen one in the form of a free-spinning shiny metal egg. Created by [David Windestål], ...

Home Assistant can control addressable LED strips, but sometimes you want more flexibility than the standard integration provides. This project uses a simple but powerful idea: A virtual light entity ...

Nick Walker didn’t secure the $750,000 prize at the 2026 Arnold Classic, but left Columbus, Ohio, with his head held high. On March 12, 2026, he discussed beating Hadi Choopan for the first time and ...

Abstract: Automated, adaptive lighting systems based on LED arrays offer significant potential for general lighting applications. Unlike conventional lighting systems, LED arrays enable real-time, ...
