Abstract

The Smart Answering Device project aims to develop an eco-friendly and efficient alternative to traditional paper-based exams, addressing both environmental concerns and the challenges of academic dishonesty in online assessments. Utilizing the Arduino Mega 2560 microcontroller, the device incorporates input components such as push buttons and a PS/2 keyboard, and output components including a I2C LCD 20x4, ISD1820 voice/audio record and playback module, buzzer module and LEDs. An android application named Smart Exam App was developed using Android Studio for lecturers to administer the exams. A HC-05 Bluetooth module is used for data transmission between Arduino and Smart Exam App. The system is designed to display exam questions, capture student responses, and provide immediate feedback through an automatic grading system. All the data that are retrieved from the exam can be stored to a lightweight SQLite database. Lastly, lecturer can use PyCharm to generate an excel file, histogram and bell curve graph for further analysis. This project not only aims to reduce paper consumption and associated environmental impacts but also seeks to enhance the integrity and efficiency of exam administration in educational settings. When talked about potential for commercialization, its large-scale adoption could transform education, stimulate economic growth, and create jobs in the technology sector. Integration with an Android app, data analytics, and strategic partnerships boost the device's adoption and drive educational technology advancements. Future work will focus on the AI integration for automated grading, enhanced display and data analytics, and lastly improved connectivity and security.
