Need help designing a digital alarm circuit
Hello, I’m looking for help with a digital electronics circuit project.
This is the circuit we currently have (image attached). I’m looking for help analyzing it — any advice, comments, or suggestions would be greatly appreciated.
These are the project requirements:
Using:
- Logic gates
- Combinational circuits
- Sequential circuits
- Flip-flops
- 1 push button
- Buzzer
- 7-segment display
I need to design a circuit with 6 inputs where, when any of them is activated, a 9-second countdown starts. Once the countdown finishes, an alarm (the buzzer) must turn on.
The push button should:
- Cancel the alarm activation if pressed during the 9-second countdown
- Turn off/cancel the alarm once it has already been activated
Any help with the logic design, circuit analysis, or implementation would really help. Thanks!
