Product description: RGB LED ring 7 x WS2812 5050
Ring composed of 7 individually addressable WS2812 RGB LEDs with integrated driver. You only need one pin of the microcontroller to operate the module. The diodes are placed in a circle with the outer diameter of 23 mm. Each of them consumes up to 18 mA, which in this case gives a total value of approximately 130 mA. The chain can be supplied with 5 V.
The communication protocol used allows the diodes to be connected in series. The next chain should be connected to the output connector, connecting respectively 5 V, GND and DOUT from DIN. The manufacturer notes that when using more than 500 diodes, there may not be enough RAM in the Arduino Uno chip.
Connection
The device has four pins:
- GND - module ground
- 5 V - supply voltage, 18 mA current per one diode
- Data IN - digital control signal from microcontroller
- Data OUT - output for connecting the next ring
Product compatible with Arduino
You can find Arduino library on GitHub for NeoPixel modules along with connection examples.
