// Simple strand test for Adafruit Dot Star RGB LED strip.
// This is a basic diagnostic tool, NOT a graphics demo...helps confirm
// correct wiring and tests each pixel's ability to display red, green
// and blue and to forward data down the line.  By limiting the number
// and color of LEDs, it's reasonably safe to power a couple meters off
// the Arduino's 5V pin.  DON'T try that with other code!

#include <Adafruit_DotStar.h>
// Because conditional #includes don't work w/Arduino sketches...
#include <SPI.h>         // COMMENT OUT THIS LINE FOR GEMMA OR TRINKET
