*// A basic everyday NeoPixel strip test program.
*
*// NEOPIXEL BEST PRACTICES for most reliable operation:
*// - Add 1000 uF CAPACITOR between NeoPixel strip's + and - connections.
*// - MINIMIZE WIRING LENGTH between microcontroller board and first pixel.
*// - NeoPixel strip's DATA-IN should pass through a 300-500 OHM RESISTOR.
*// - AVOID connecting NeoPixels on a LIVE CIRCUIT. If you must, ALWAYS
*//   connect GROUND (-) first, then +, then data.
*// - When using a 3.3V microcontroller with a 5V-powered NeoPixel strip,
*//   a LOGIC-LEVEL CONVERTER on the data line is STRONGLY RECOMMENDED.
*// (Skipping these may work OK on your workbench but can fail in the field)
*
*#include <Adafruit_NeoPixel.h>
*#ifdef __AVR__
* #include <avr/power.h> // Required for 16 MHz Adafruit Trinket
*#endif
*
*// Which pin on the Arduino is connected to the NeoPixels?
*// On a Trinket or Gemma we suggest changing this to 1:
*#define LED_PIN D3
*
*// How many NeoPixels are attached to the Arduino?
*#define LED_COUNT 60
*
*// Declare our NeoPixel strip object:
*Adafruit_NeoPixel strip(LED_COUNT, LED_PIN, NEO_GRB + NEO_KHZ800);
*// Argument 1 = Number of pixels in NeoPixel strip
*// Argument 2 = Arduino pin number (most are valid)
*// Argument 3 = Pixel type flags, add together as needed:
*//   NEO_KHZ800  800 KHz bitstream (most NeoPixel products w/WS2812 LEDs)
*//   NEO_KHZ400  400 KHz (classic 'v1' (not v2) FLORA pixels, WS2811 drivers)
*//   NEO_GRB     Pixels are wired for GRB bitstream (most NeoPixel products)
*//   NEO_RGB     Pixels are wired for RGB bitstream (v1 FLORA pixels, not v2)
*//   NEO_RGBW    Pixels are wired for RGBW bitstream (NeoPixel RGBW products)
