Create _255_255_255_in_array_to_neopixel

This code leverages the adafruit neopixel library
it reads the inputs from potentiometers or photoresists, scales and re-maps the readings to 0-255 values, then calculates the color number for the neopixel library.
the color is read into an array, and propagated down the array, and loaded into the neopixel.
The results is that a new color is placed on the strip, and travels down the strip, and off the end.
