// Which pin on the Arduino is connected to the NeoPixels?
// On a Trinket or Gemma we suggest changing this to 1
#define PIN
// How many NeoPixels are attached to the Arduino?
#define NUMPIXELS
// When we setup the NeoPixel library, we tell it how many pixels, and which pin to use to send sig-
nals.
// Note that for older NeoPixel strips you might need to change the third parameter--see the strand-
test
// example for more information on possible values.
