Digital Systems Design Individual Project

Introduction

For this project, we are to design a large 7-segment based display that shows the time (including seconds) using decade counter ICs. We first should design the circuit in Logisim and then design a PCB for the circuit using EasyEDA.


Our design should meet the following requirements:

Logisim Simulation

For my individual design, I attempted to use flip-flops instead of the decade counter ICs to design the clock. However, I was unable to get a 12-hour clock, although the 24-hour clock works perfectly. I was also unable to get the clock to beep after every 15 minutes.
