Single wire communication, to maximize the reduction of I/O port pressure, and the use of the RGB WS2812B driver chip, so that the peripheral circuit requires only a single capacitor can meet the needs of the circuit, give people the enjoyment of beauty, in addition, this RGB ring, but also through a simple Dout input port, and the other using the same chip RGB lamp cascade, without need considering the shape of the limit.
