24 Shot Clock with Buzzer Multisim

[Jaxton Joseph]

Hello Good Day!

I currently need help in this laboratory assignment to be designed via Multisim.

Details of Laboratory:
The task is to create down timer starts from 24 to 0.
- Initial condition is 2 7-segment will display 2 and 4 respectively
- The timer will start when the user triggered a push button labeled as “start”
- When it reaches zero “0” there will be a buzzer that will activates, and it will keep buzzing until the user triggered the “reset” button.
- Once “reset” is triggered, the device will enter the initial condition
- There is a need to have a “pause” button that will temporarily pause the timer.

Input:
Input will be 3 buttons Start, Reset/Stop and Pause.
Start button – triggers the timer functionality
Pause button – pause the timer functionality
Stop/Reset Button – Stops the buzzer and resets the device to initial condition

Output:
Two 7-segment display

Any help or idea is much needed. Thank you very much!

You crack on... Come back when the circuit is done and not working, someone will then tell you where to look to get it going.

You must show that you are keen to learn, as we already have done..
