Wiring up this project is really simple. All you need to do is connect the following:

Feather HUZZAH pin -> Neopixel pin:

• HUZZAH GND -> Neopixel #1 (G)
• HUZZAH 5V -> Neopixel #1 (+)
• HUZZAH Pin (4) - Neopixel #1 (In)

After you wire up the Feather HUZZAH to the first of your Neopixels just connect all subsequent Neopixels together: (Just make sure out from #1 goes to In of #2)

• Neopixel #1 (G) -> Neopixel #2 (G)
• Neopixel #1 (+) -> Neopixel #2 (+)
• Neopixel #1 (Out) -> Neopixel #2 (In)

And then add a few more if needed: (I added a 3rd Neopixel)

• Neopixel #2 (G) -> Neopixel #3 (G)
• Neopixel #2 (+) -> Neopixel #3 (+)
• Neopixel #2 (Out) -> Neopixel #3 (In)

You can solder them all together, or you could use female to female jumper wires, which is what I chose to use. Why? Becasue I realise that I'm the kind of maker that likes to constantantly modify and reuse parts so I wanted it all to come apart easily for a future project.
