PROJECT DESCRIPTION

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.

Q & A
Q:  Where is this project used?
A:  This project can be implemented at schools, colleges, where quiz competitions are held.
Q:  How many switches are provided with this project?
A:  About 8 switches are provided with this project, along with 8 LEDs.
Q:  Which microcontroller is used in this project?
A:  No microcontroller is used is in this project.
Q:  What is the formula for calculating smoothing capacitor value?
A:  There is some approximated formula .Peak to peak ripple voltage = Load current in amps / (2*line frequency in hertz *capacitance in farads). But as rule of thumb for 1 A current 1000uF is best. Thus it is load dependent.

Thank you Kamini for your greetings.
I not only got the kit I ordered from EdgeFx on time but professionally packed and of course it worked perfectly fine. I really enjoyed finding the solution that I needed in such a short span of time and I look forward to purchasing more kits from EdgeFx both to enhance my knowledge and to help my students learn better. I remember the days when I used to fabricate the PCBs at home (including etching) to develop our circuits. Today, thanks to companies like EdgeFx you have much more sophisticated kits available at our finger tips.
Thanks again for maintaining professional quality in all that you do. Wishing you the very best.
