// Simple NeoPixel test.  Lights just a few pixels at a time so a
// 1m strip can safely be powered from Arduino 5V pin.  Arduino
// may nonetheless hiccup when LEDs are first connected and not
// accept code.  So upload code first, unplug USB, connect pixels
// to GND FIRST, then +5V and digital pin 6, then re-plug USB.
// A working strip will show a few pixels moving down the line,
// cycling between red, green and blue.  If you get no response,
// might be connected to wrong end of strip (the end wires, if
// any, are no indication -- look instead for the data direction
// arrows printed on the strip).
