+neopixel_spi v03
+Created By: Ivan Yohuno
+SSID: 200717683
+
+Notes:
+-Code to be run on WS2812 neopixel LEDs, can run with a single pixel or a strip of max 8 leds connected together
+-Single LED can be connected to power source of 5V but if connected to 5V logic will need to be shifted up from 3.3V to 5V
+
+Features:
+-SetRGBPixel // sets colour of one RGB Pixel (the first pixel connected), generally used for testing. Colour is a mix of 3 8 bit values of red, green and blue
+-SetRGBStrip // sets colour of RGB strip of 8
+-setRGBStrips //sets colours of 4 RGB strips of 8
+ colours 2D 4x3 matrix:
+ {{room 1 strip red, room 1 strip green, room 1 strip blue},
+ {room 2 strip red, room 2 strip green, room 3 strip blue},
+ {room 3 strip red, room 3 strip green, room 3 strip blue}
+ }
+-SetRGBPixels // sets an RGB strip of 8 to individual colours using a 2D 8x3 matrix
+ colours 2D 8x3 matrix:
+ {{1st pixel red, 1st pixel blue, 1st pixel green},
+ {2nd pixel red, 2nd pixel blue, 2nd pixel green},
+ {3rd pixel red, 3rd pixel blue, 3rd pixel green},
+ {4th pixel red, 4th pixel blue, 4th pixel green},
+ {5th pixel red, 5th pixel blue, 5th pixel green},
+ {6th pixel red, 6th pixel blue, 6th pixel green},
+ {7th pixel red, 7th pixel blue, 7th pixel green},
+ {8th pixel red, 8th pixel blue, 8th pixel green}
+ }
