Prep Wires
Let's start by making a set of wires for connecting our components.
We'll need 5 pieces of wire about 8cm in length. I suggest using 26AWG silicone coated stranded wires.
Remove about 3mm of insulation of from the tips of each wire. Apply solder to the tips to tin them - this prevents wires from fraying.
Tap Mounting Holes
We'll need to create threads in the two mounting holes of teh Adafruit Feather HUZZAH board. You can use a 4-40 tap drill or a 4-40 machine screw.
Prep Slide Switch
Trim leads short to about half their size. Remove one of the three leads from the slide - either the far left or right. Apply solder to the two remaining leads to tin them.
Wire Slide Switch
Connect one wire to each lead by heating up the tip of the lead and placing the tip of the wire.
Slide Switch
You can optionally apply some pieces of heat shrink tubing to insulate the exposed areas. The slide switch is now ready!
Wire NeoPixel Ring
Apply solder to data in, ground and pwr +5V pins on the NeoPixel ring. Then, connect three wires to these pins on the NeoPixel ring.
Wire Slide Switch to NeoPixel Ring
Connect one of the wire from slide switch to GND pin on NeoPixel.
Wire NeoPixel to Adafruit Feather
Connect the three wires from NeoPixel to Adafruit Feather HUZZAH.
- Data in from NeoPixel to Pin #14 Adafruit Feather Huzzah
- Ground from NeoPixel to gnd on Adafruit Feather Huzzah
- 5V PWR from NeoPixel to USB on Adafruit Feather Huzzah
- Wire from Slide switch to EN on Adafruit Feather Huzzah
Test Circuit
The arduino code should already be uploaded to the Adafruit Feather Huzzah. Connect a microUSB cable to your computer (or a 5V power supply) and to the HUZZAH board. NeoPixels should power on!
Install HUZZAH
Lay the board over the standoffs and align up with screw threads with the moutning holes. Fasten screws until board is secured in place.
Install NeoPixel Ring
Add pieces of mounting tack to case, press NeoPixel ring into case. Secure in place. Be cautious not to kink any wires!
Install Cover
Install the cover by twisting it onto the case like a bottle cap. It has threads, like a twisty top!
