DIY Custom Arduino to Neopixel Cable

in this video we use some 22 AWG stranded wire, .254 male header pins, and .254 female header pins to create a custom DIY Arduino to Neopixel cable. Note the 2 grounds. because the WS2812B(neopixels) are usually powered separately from the Arduino there is a second ground. Wiring goes GND and VCC to external 5VDC source, IN and GND go to the Arduino. Since the grounds are connected between the board and the Arduino everything is at equal potential.
