#include <Adafruit_NeoPixel.h>


#define PIN 6

// Parameter 1 = number of pixels in strip
// Parameter 2 = Arduino pin number (most are valid)
// Parameter 3 = pixel type flags, add together as needed:

Adafruit_NeoPixel strip = Adafruit_NeoPixel(13, PIN, NEO_GRB + NEO_KHZ800);



void setup() {
 
  strip.begin();
  strip.show(); // Initialize all pixels to 'off'
}

void loop() {
  // Some example procedures showing how to display to the pixels:
  colorWipe(strip.Color(255, 0, 0), 50); // Red
  colorWipe(strip.Color(0, 255, 0), 50); // Green
  colorWipe(strip.Color(0, 0, 255), 50); // Blue


  rainbow(20);
  rainbowCycle(20);
