+Typically, neopixels reqire VCC, VSS (GND) and DI pins connecting to the
+Raspberry Pi, where the DI pin is usually connected to a PWM control pin
+such as GPIO 18.

+The DO pin should be connected to the DI pin on the next (daisy-chained)
+neopixel, while the VCC and VSS are supplied in-parallel to all LED's.
