RGB 5050 LED Ring with Driver - WS2812B - 8 Bits

A ring consisting of 8 WS2812B RGB LEDs with integrated driver, which are individually addressed. The module is operated with a single cable.
The LEDs are located on a 23mm diameter circle in an even manner. Each of them consumes 18mA (144mA in total). The ring is powered by 5V.
The communication protocol allows the diode modules to be connected in series. Another string is connected to the output connector. interconnecting 5V, GND, DOUT with DIN. If more than 500 LEDs are used, the RAM in the Arduino Uno may run out.

Connection

GND - module ground
5 V - supply voltage, 18 mA current for one diode
Data IN - digital control signal from the microcontroller
Data OUT - output for connecting the next ring
