The WS2812B LED is characterized by its ability to emit light in red, green or blue as well as combinations of these three colors, allowing for a palette of about 16 million colors. The LEDs are arranged in a circle and can be controlled with just a few lines of code from the Arduino IDE, thanks to the integrated controller in each LED. https://elecena.pl/product/25816073/333055-developer-boards-led-ring-rgb-7-leds-ws2812 2024-05-06 https://elecena.pl/product/25816073/333055-developer-boards-led-ring-rgb-7-leds-ws2812 2025-02-08 https://elecena.pl/product/25816073/333055-developer-boards-led-ring-rgb-7-leds-ws2812 2025-04-07 https://elecena.pl/product/25816073/333055-developer-boards-led-ring-rgb-7-leds-ws2812 2025-09-04
