 * Notes:   Simple test program to demo NeoPixels
 *          One pixel races round the ring or down the strip set to one color (let's call it the  
 *          'foreground' color); the pixels "behind" it are set to another color (let's call it
 *          the 'background' color).

//   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)
