OBJECTIVE
• Familiarisation & Implementation Of Electronic Jam
INTRODUCTION
• Electronic Jam Is Commonly Used In Quiz Contests• Fastest Finger First Is The Basic Principle• It Adds Beauty To Active Quiz Shows Contains Many
Buzzer Rounds• 8 Inputs Can Be Handle At A Time• Uses Seven Segment Display Instead of LED/bulb
For Visual Interface• This Electronic Jam Is Built With The View Of Making
The Game Show Priority Less

WORKING
• 8 Input is fed to edge triggerd flip flop
APPLICATIONS
• It can be used in quiz contests Game Show Priority Less
• It can also be used in voting machines where, if a voter presses a button the LED lamp glows & the buzzer rings. Once a button is pressed all the other buttons are jammed. The officer has a switch to reset the voting machine after each voter votes.
ADVANTAGES
• Handy device• Low power consumption• More accurate• Easy to use• Visual interface adds its advantage
DIS ADVANTAGES
• Input is limited to Eight
Future Scope
• Instead of Seven Segment display LCD screens can be implemented
• Priority list of all inputs can be imparted in output
CONCLUSION
• Project Aims the Implemenatation of ‘Electonic Jam’ for making Quiz shows priority Less
• Seven Segment display included for more User Interface
