Rainbow LED Ring V3 (Arduino Compatible)

The Rainbow Ring board has been upgraded to version 3! This is probably the most beautiful LED ring ever. Each led on the ring can be controlled desperately on its brightness and colors (RGB). It comes with pre-burned bootloader which has several built in led scripts.

This Rainbow LED Ring V3 allows I2C/Serial communication from any MCU and can be serially linked to make a beautiful Art piece via I2C.
