The great thing about this NeoPixel is that we can take the control of it from your Arduino sketch.

We just need to know the pin to use ('''pin 8''') and install the Adafruit NeoPixel Library for ATSAMD21 microcontroller :-)
The NeoPixel should be viewed as the very first LED of a NeoPixel Strand having only one single LED.

The following script demonstrate how to manipulate the onboard NeoPixel.
The following script demonstrate how to manipulate the onboard NeoPixel.
As there is only one pixel (one pixel on the strand), the function {{fname|pixel.setPixelColor()}} will always have the first parameter is set to 0!
This means that we change the color of the LED #0 on the ''pixel strand''.
