Digital Logic 24H Clock PCB

Summary

This was my first project involving ECAD software. Prior to this project I had only been exposed to basic breadboarding and Arduino shields for creating electronic circuitry. The goal of this project was to implement a digital 24 hour clock (HH:MM:SS format) using only digital logic ICs on a custom PCB design. Autodesk Eagle was used to design schematics and physical layout, and Autodesk TinkerCAD was used to validate basic sub-circuit behaviour.
