+// Parameter 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)

+// IMPORTANT: To reduce NeoPixel burnout risk, add 1000 uF capacitor across
+// pixel power leads, add 300 - 500 Ohm resistor on first pixel's data input
+// and minimize distance between Arduino and first pixel.  Avoid connecting
+// on a live circuit...if you must, connect GND first.
