Boeing Project Wiring Diagram

Here is the full wiring diagram for the project. We did the project on two separate breadboards because when we began, we underestimated the amount of space the components required. This project could also be completed on one large breadboard.

stockmarketproject.ino

Arduino
This is the software that we developed that runs the whole project. We uploaded this code onto a Particle Photon.
