Korean OLED TVs, long considered the gold standard for premium television, are facing growing competition from Chinese and Japanese manufacturers as they roll out next-generation RGB LED TVs. At CES ...

A youtuber has developed a lighting system for staircases using the ESP32 module, the RD D03E mmWave radar sensor, and the WS2812 RGB LED strip. The system dynamically illuminates stairs based on a ...

Built around an ESP32-S3 wireless MCU, it features a 1.28” capacitive touch display (240×240), and a UI designed with LVGL/Squareline and the Arduino V2.3.4 IDE. The device relies on a BT139 Triac and ...

The Raspberry Pi 5 already has composite video out, but now it can do interlaced RGB via DPI for sharper CRT output via SCART. If you want composite video output, the Raspberry Pi 5 includes this via ...

Abstract: We propose an optical camera communication (OCC) system with dimming control, employing wavelength division multiplexing (WDM) with RGB and infrared (IR) light sources. The system uses pulse ...

A few years ago [Brian McCafferty] created a nice big RGB LED panel in a poster frame that aimed to be easy to move, program, and display. We’d like to draw particular attention to one of his ...

In this project, Smart Toll Tax System using RFID and Arduino, we aim to create a contactless, automated toll… ...

These are actually really neat, they look good and are relatively cheap. It’s a string of RGB LEDs with drivers, each dipped in epoxy, and run on a common three-enameled-wire bus. Unlike WS2812s ...

An Arduino NeoPixel support library supporting a large variety of individually addressable LEDs. Please refer to the Wiki for more details. Please use the GitHub Discussions to ask questions as the ...

The following shows the absolute minimal wiring setup e.g. for the ESP32 DevKitV1. It may differ depended on your development board. ⚠️ If you power the development board and the LED matrix via USB: ...
