We recommend using the WS2812B Arduino Library that came installed with the board add-on. Below is a modified example of the WS2812B_Basics.ino sketch since we the LED is on the secondary SPI port and ...

WS2812B & Arduino Earlier we controlled LED matrixes, strips and other complex LED projects bundled with countless interconnected wires with the help of multiplexers and shift registers.

An example sketch is available that shows how to use the library. You can access it from the Arduino IDE by opening the "File" menu, selecting "Examples", and then selecting "ws2812B-arduino".

SPI to WS2812B converter 3 ways to make SPI compatible with WS2812B-type addressable RGB LEDs. For the WS2812B-type addressable RGB LED (also known as 'NeoPixel') a logic ‘0’ is expected to be a pulse ...

Use SPI for talking to WS2812(B)-type addressable RGB LEDs (a.k.a. NeoPixels) and control 25% more LEDs while freeing up MCU resources at the same time.
