FASTEST FINGER PRESS QUIZ BUZZER
ABSTRACT
A set of 8 switches are interfaced to D-type flip flop
working as priority encoder. While number of switches is pressed at same time,
it takes the first switch pressed into consideration and generates a buzzer sound
along with the indication of the switch pressed.
This circuit includes 8 numbers of push buttons which are
fed to a D-type flip-flop. This flip-flop generates o/p signal which is fed to
a transistor, making the corresponding LED to switch ON and also generates a
buzzer sound.
Further the project can be enhanced by using a display to
indicate the order in which switches are pressed.
