Datasheet

You can set the overall brightness, this is a one time 'nonreversable' setting, so once you

set pixel colors they will automatically be scaled by the brightness. 0 is all the way off, 255

is all the way on. Default is 255.

strip.setBrightness(200); // Adjust as necessary to avoid blinding

Then you can set each pixel color with

strip.setPixelColor(n, red, green, blue);

Where n ranges from 0 to numberOfPixels-1 and red, green and blue are the RGB

component color, ranging from 0 (off) to 255

For example, to set pixel #1 to full red:

strip.setPixelColor(0, 255, 0, 0);

To set pixel #5 to a dim green-blue

strip.setPixelColor(4, 0, 30, 30);

Once the pixel colors are set, you'll need to tell the pixie strand to update, call:

strip.show();
