Steps:
- Construct the wires for the neopixel strip.
(If you have not solder you should solder the strip with three wires and one resister attach to the pin wire.)
2. Next solder the accelerometer parts together
3. Put the accelerometer wiring together using the female/male wiring
4. To make the connectivity all the same, Wire the the that use the same pins. To take the breadboard away.
5. Hot glue the strip to the hat. Hide the wires under the hat and tape the ardunio and wires. Since everything is programmed use the battery instead of the computer now.
