This project was undertaken as part of the final assignment for the Digital Techniques course at the Faculty of Engineering, Universitas Negeri Yogyakarta. In this project, my team and I designed and built a digital clock using IC 74192 and Seven Segment Displays. The goal was to create a functional digital clock circuit while deepening our understanding of digital components and their interaction. The IC 74192 was used as a counter to count seconds and minutes in BCD (Binary Coded Decimal), while the Seven Segment Displays were utilized to visually display the time in a readable format. Additionally, AND gates were incorporated to select and reset the clock, ensuring that the counting operation followed a modulo 60 cycle, suitable for displaying minutes and seconds.
The project was successfully simulated and tested using Electronic Workbench, allowing us to validate the circuit’s design before physical implementation. This experience provided valuable insights into the fundamentals of digital systems, including counters, decoders, and combinational logic, as well as the challenges of synchronizing multiple digital components. The digital clock operates smoothly, displaying accurate time and including a reset function to initialize the clock when needed.
