The Rainbow Ring V3 is a compact RGB LED ring in which each LED can be individually controlled for brightness and color (RGB). It features a pre-burned bootloader with built-in lighting scripts and supports I2C and serial communication with any MCU. Multiple rings can be daisy-chained via I2C to create synchronized lighting effects and artistic installations.
