NeoPixel

NeoPixel Wires

We'll need three new pieces of wire to connect the NeoPixel stick to the Adafruit Feather. These were slightly longer than the Feather PCB, so about 10cm in length should be fine. Using wire stripper, I removed a bit of insulation and applied a bit of solder to tin the tips of each wire. A piece of shrink will keep the wires bundled together.

Connect Wires to NeoPixel

Now we can work on connecting the wires to the NeoPixel stick. I found the components fit best with the wires oriented towards the PCB, as opposed to pointing outwards. I made sure to tin the ground, power and data in pads on the NeoPixel stick before attaching the wires. 

Connect NeoPixel to Feather

Next, I connected the wires from the NeoPixel stick to the Adafruit Feather. Make sure to connect power from the NeoPixel to the 3V pin on the Adafruit Feather – I mistakenly soldered it to a free pin near the prototyping area. The data in wire can go into any pins, but I choose pin number 6. The ground wire can connect to any of the available ground pins.

Test NeoPixels

If the code has been uploaded to the Adafruit Feather, we can test out the circuit. So if you haven't done so, now is a great time to do so! At this point, it's a good idea to double check the wiring, maybe even shorten them or tidy them up.
