Product description: Adafruit NeoPixel Ring - ring LED RGB 24 x WS2812 5050
Ring consisting of 24 individually addressed WS2812 RGB LEDs with integrated driver. One microcontroller pin is sufficient to operate the module. The LEDs are placed at equal distances on a circle with an external diameter of 66.0 mm. Each of them draws a current d of 18 mA, which in this case gives a total value of approx. 450 mA. The chain is supplied with 5 V.
The applied communication protocol allows for serial connection of diodes. Another chain should be connected to the output connector, connecting 5V, GND and DOUT with DIN respectively. The manufacturer notes that when using more than 500 diodes, the Arduino Uno RAM memory may not be sufficient.
Connection .
The device has four leads:- GND- module weight
- 5 V- supply voltage, 18 mA of current per diode
- Date IN- digital control signal from the microcontroller
- Date OUT- output for connecting the next ring
