Bill of Materials
A bill of materials or BOM for short, is list of the materials and parts used to create an end product.
Ths includes all the parts used for making the wiring diagram prototype. I also added additional components, such as the materials for the casing of the product.

Wiring Diagram
A wiring diagram is a simplified representation of an electrical circuit, which shows the power and signal connections between the components, this includes information on wire colors among other things.
This is the complete wiring diagram for the product. You can recreate this using the components mentioned in the BOM.
The color codes for the wires are as follows:
| Wire Type | Color |
|---|---|
| 3.3V | Red |
| GND | Black |
| Digital Input | White |
| Digital Output | Blue |
