Fingerprint Scanner

My first big project utilizing microcontrollers and Arduino. I couldn’t figure out which complexities I wanted to add to my project so I ended up using a cluster of them to communicate to and from each other.

I tinkered a lot with serial and parallel communication in this project. Even though you can mostly achieve the same result for both types of communication, I wanted practice both in case I ever come across a need to implement one or the other.
