Summary
The digital quiz system is designed to minimize the error and to save the time. This system is
designed for an oral type of test or examinations, and it leads towards the accuracy of the result.
The system consists of a judge and four participants. In which a judge will ask a question from
the participants and the one who know the answer, will press the button first and then it will be
displayed on the 7-segment display (screen) that which participant have pressed the button and
he will answer the question. The one who presses the button first, only he will be able to answer,
then the other participants will not be able to give the answer. Which means at a time only one
participant can answer to a question. After giving answer to the question, the judge will press his
button and if the answer is correct the marks will be displayed on the 7-segment display (screen)
of the respective participant. If the answer is wrong, the judge will not press the button which
means the answer is incorrect and there will be no increment in the marks of the respective
participant. However, the whole circuit consist of two main parts. The first part is for the
participants and the second part is for the judge. In the first part the seven-segment display is
used to display the selected user and in the second part the seven-segment display is used to
display the corresponding scores of every participant.
The main purpose of the system is to:
 Save the time.
 Accuracy in the result.
 Promote digital system.
 Prevent cheating.

1. Introduction
The digital quiz system selects one user from four users in a quiz competition and displays
their result using seven segment displays. The circuit is consisting of two major parts. The first
part is for the users and the second part is for the checker. In the first part of the circuit the
system will only choose the user who has toggled the bottom at first and allow the user to
answer, and now in the second part of the system the checker will decide whether to
increment the score or not based on the answer given by the user. Each part of the systemis
connected with a seven-segment display. In the first part the seven-segment display is used to
display the selected user and in the second part the seven-segment display is used to display
the corresponding scores of every user.
First Part
The first part of the Digital Quiz System consists of:
1. OR Gates
Or gates are used in which any input or both inputs are high, the output will be
high.
2. NOT Gates
Not gates are also used in which if the input is high the output will be low or if the
input is low the output will be high.

3. Feasibility
The feasibility of the project is described below.
3.1. Time Frame
The time frame forthe projectwas almost twomonthsand the projectwasdividedintotwoparts.
The first part of project was to design it on a software. Because if we design a circuit physical and
there isan error, so we are not able to extracterror.First,we have designitona software andrun
a system on it. If the circuit is correct, the software will run and if there is an error during circuit
designing thenthe project will not run, and it will show error. The second part of the project is to
implementthe circuit.Thishappensafterthe circuitisdesignedcorrectlyonthe software,thenitis
easy to design a circuit physically.
3.2. Merits and Demerits
There are manyadvantagesanddisadvantagesof digital quizsystem,whichhave beendiscussedas
follow:
 Merits
The benefits of digital quiz system is:
 Environmentally Friendly.
 Economical.
 Quick turnaround time.
 Highly secure.
 Easy to use.
 Auto grading.
 Demerits
Looking toward the demerits of the system. Some of the demerits are given that:
 there is a chance of damage inside the circuit.
 a short circuit can lead towards the fire.
 a single connection can damage the whole circuit.
 Only one student can answer at a time.
4. Conclusion
The constrain of project and its development, future works that can be taken into
consideration and eventually conclusion will be discussed. The contribution of digital quiz
systemis to support lecturers and students to conduct an oral type of quiz. This systemcan be
used by the lecturers to evaluate students effectively, efficiently, and perfectly. Besides that,
this system reduces the time for lecturers on grading students. In this system students will

13. Digital QuizSystem

automatically be graded at the end of the quiz. Moreover, this method is more effective to
prevent problem in manual quiz procedure.
This project more focus on the problems faced by the lecturers in manual system. For instance,
the losing of quiz papers, no pencil, and pens for checking. Also, the lecturer spends his time
in gradings. All these problems can be solved by introducing a digitalized quiz system. In which
the students will not require to carry their pens and paper for the quiz, and it is an oral type
of quiz. To save the time of the lecturer the student will automatically get their scores after
the quiz. In addition, this kind of system can be replaced by the manual system in order to
increase the efficiency of the quiz management. The process to build up this system takes a
long time, so that the insufficient time problems should be faces and solved. To ensure the
good quality of the systemthe time management is most important to build up a good system.
In order to make sure the system can run well and meet the user requirements; the
improvement should be done, and the problem of insufficient time should be solved.
5. Recommendation
The digital quiz system is not connected to any internet service so there is no chance for the
student to cheat from any source. So, when the proposal was submitted, it was highly
recommended to design such a system to conduct a quiz and is user friendly and easy to use.
Then observation, planning and working for the project was started. Project was very difficult
but interesting too. Discussion was made different ideas were shares between the group
members of the project and finally after a teamwork, project comes to end with success. But
it was observed that, the one who is sharp minded will get the question from the instructor
and will respond in no time.
