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 ...

Lasers, LEDs and light sources are devices that create light. LEDs (light emitting diodes) convert an electrical current into light using spontaneous emission in optically active semiconductors.

On paper, LED bulbs are made to last for at least several years thanks to their low energy needs. I wanted to know why that doesn't always work out, so I talked to installers and LED manufacturers to ...

While smartphones technically give us a flashlight in our pockets wherever we go, they work largely for finding your keys under a movie theater seat or helping you reach the light switch in a pitch ...
