RGB LED Ring Colorful Light Module

The 12-bit RGB light ring is composed of 12 WS2812RGB lamp beads connected in series. Only one IO port is needed to drive this module. A chip is integrated inside the WS2812 RGB lamp. We only need a single IO port to control the WS2812RGB lamp. The D pin is the signal output and can be connected in series to the next lamp bead. The R pin is the signal input to control the color of the RGB lamp beads and the number of series connections. The V pin is the positive pole of the power supply, and the G pin is the negative pole of the power supply.
