== Test script ==
The following script demonstrate how to manipulate the onboard NeoPixel.

void setup() {
pixel.begin();
// switch OFF the pixel 0
pixel.setPixelColor(0, pixel.Color(0,0,0));
pixel.show();
}
int red = 0;
int green = 0;
int blue = 0;
void loop(){
pixel.setPixelColor(0, pixel.Color(red,green,blue));
pixel.show();
red += 10;
if( red > 255 ){
red = 0;
green += 10;
}

blue += 10;
}
if( blue > 255 ){
blue = 0;
}
