Project Description

This Digital Systems Design project entails the design of a digital clock circuit using the 74161 hex counter IC. The 12-hour clock created can opearte from the mains, be set, and buzzes every 15 minutes.

Also included on this page are PCB schematics and designs of an individual seven-segment digit.
