Digital Logic Term Project: BCD Clock

Objective

Using your expert Digital Design Skills, design a 24 hour digital Clock that displays the time in Binary-Coded-Decimal.

Digital Clock Design Requirements -

To aid the design process, the power supply and clock divider subsystems design schematics are shown in Figures 1 & 2. You must finish the design by using counters, combined with the appropriate reset logic, to count the seconds, minutes, and hours of the day. Additionally, the final design at a minimum should include:

A 24 Hour BCD display that shows

Hours
Minutes
Seconds

A Set Time Button along with:

Set Hours Button
Set Minutes Button
Set Seconds Button
The operation should be such that when the "Set Time" button is depressed, the clock temporarily stops counting and you can manually push the Hours/Minutes/Seconds button to increment "set" those counts"

A 9V source powered by a:

9V Battery or
9V Power Supply

Soldered Prototype (Perf) Board

A Project Box to enclose the final board. It could be

Clear or
A Transparent Color

Report Requirements -

Please provide a full report describing your design, including Schematics and a full description of each subsystem, i.e. Power Supply, Clock Divider, Hours, Minutes, Seconds counters etc.

Please note that you may be requested by the department to donate your project at the end of the term.

Parts List

The following parts list should provide you with the minimum parts required to build the standard BCD clock. All ICs used are to be CMOS, not TTL. Be sure to order DIP parts. Please note that the following are NOT included in the parts list:

The Perf-board or PCB material
The parts for the extra credit 7-segment display subsystem
The parts for switch debouncing
The project housing and any packaging/casing material you may wish to use

You are a digital systems engineer working on a critical mission for the space program on Mars. Your director, Dr. Extrater Restrial, has asked you to design a custom Digital Clock as a piece offering to the Martian inhabitants. The only catch is that the Martians only understand binary coded decimal. Please provide a full report describing your design, including Schematics and a full description of each subsystem, i.e. Power Supply, Clock Divider, Hours, Minutes, Seconds counters etc. Please note that you may be requested by the department to donate your project at the end of the term.
