60-Second Timer Project Overview
60-Second Timer Project Overview
Students must create a 60-second timer that counts from 0-59 and then resets to 0. The timer will consist of synchronous counters and seven-segment displays that output the number sequence
Criteria
Criteria
The circuit will count from zero to 59 and reset back to 0.
A reset switch needs to connect to all the clears in both counters.
A switch is required to reset the circuit.
Constraints
Constraints
Synchronous counters must be used.
Students use JK-Flip Flops for the ten’s display.
Students use 74LS163N MSI for the one’s display.
Common-cathode SSD must be used.
Video Demonstration
Video Demonstration
The video shows the sketch of the circuit and the circuit in Multisim. The count starts at 0 and resets at 59; the reset switch overrides both counters and resets the count back to 0 at any point.

Review of Project
Review of Project
The project succeeded overall as the circuit worked correctly, following all the criteria and constraints. Little problems were encountered and were solved appropriately.
Problems and Solutions
Problems and Solutions
One setback was implementing a reset switch. The solution was adding an AND gate with the clears on both counters.
