-**CODE**
- // 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    6
-
- // 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)

- }

- // loop() function -- runs repeatedly as long as board is on ---------------

- void loop() {
-  // Fill along the length of the strip in various colors...
-  colorWipe(strip.Color(255,   0,   0), 50); // Red
-  colorWipe(strip.Color(  0, 255,   0), 50); // Green
-  colorWipe(strip.Color(  0,   0, 255), 50); // Blue
-
-  // Do a theater marquee effect in various colors...
-  theaterChase(strip.Color(127, 127, 127), 50); // White, half brightness
-  theaterChase(strip.Color(127,   0,   0), 50); // Red, half brightness
