Digital Eight-Channel Quiz Timer Based on Multisim
(Simulation + Demonstration Video + Design Report)
01
Function Introduction
Simulation Function:
1. Design a digital quiz buzzer, with each team having a buzzer button.
2. The circuit has the function of identifying and latching the first buzzer signal.
3. After the host presses the start button, the contestants begin to buzz in. When the first contestant buzzes in, the system latches, preventing other contestants from buzzing in. At the same time, the countdown timer pauses, an audible and visual alarm is triggered, and the digital display shows the number of the first contestant who buzzed in.
4. A timing circuit is set up, and when the timer expires without any contestant buzzing in, the circuit latches to prevent contestants from buzzing in, triggering an audible and visual alarm, and the host can reset the system.
