// NeoPixel Ring simple sketch (c) 2013 Shae Erisson
// released under the GPLv3 license to match the rest of the AdaFruit NeoPixel library
#include <Adafruit_NeoPixel.h>
#ifdef __AVR__
#include <avr/power.h>
// Which pin on the Arduino is connected to the NeoPixels?
// On a Trinket or Gemma we suggest changing this to 1
#define PIN 6
// How many NeoPixels are attached to the Arduino?
#define NUMPIXELS 8
// When we setup the NeoPixel library, we tell it how many pixels, and which pin to use to send signals.
// Note that for older NeoPixel strips you might need to change the third parameter--see the strandtest
// example for more information on possible values.

void setup() {
pixels.begin(); // This initializes the NeoPixel library.

// For a set of NeoPixels the first NeoPixel is 0, second is 1, all the way up to the count of pixels minus one.
int count = NUMPIXELS;
for(int i=0;i< NUMPIXELS;i++){
// pixels.Color takes RGB values, from 0,0,0 up to 255,255,255

int b = flicker / 2;
pixels.setPixelColor(i, pixels.Color(r, g, b));; // This sends the updated pixel color to the hardware.
delay(random(30,50)); // Delay for a period of time (in milliseconds).
