Abstract
The goal of this project is to make the educational process more interactive, in order
to grab student interest, but also to enable students who are reluctant to tell their queries to
have their say anonymously. At the same time, the application gives instructor the ability to
extract in real time useful conclusions for the course, since the system processes the
responses of students by exporting charts and storing it for future use. Students will be able
to give their opinion by voting through the website of the application, which can be accessed
via computer, tablet, mobile phone and by any device can connect to the internet. Otherwise,
students will be equipped with small devices, which have five (5) buttons. When the
instructor deems it appropriate, he asks questions in multiple-choice format and students
have to choose the correct answer. Each device consists of an Arduino Uno, an Arduino
WiFi Shield for internet connectivity and five buttons (push-buttons). Each button of the
device corresponds to one of the possible answers provided. Each voting machine has a
specific id and connects wirelessly via Internet to the database system. The website and the
database of the system are programmed in php/mysql. The operation of the system is to
extract graphics concerning the responses of students and to store data.
