An RFID-Based Library Management System Using ATmega32 Microcontroller

Automation is the way forward to enhance outdated methods of doing things in this era. Library management, which is sometimes dependent on manual doing, is time-consuming and is marred with issues such as errors and incorrect information. This paper demonstrates how to construct a Library Management System based on RFID and an ATmega32 microcontroller. The system employs RFID to enable auto-check in and check out of books by uniquely tagging books and users. When the user scans the RFID card and the tag of the book, the chip verifies the information and performs what it needs to. Messages are displayed on a screen, and the information is stored. The system also includes buzzers, lights, and buttons to make it simpler to use. This system speeds up library work, has better records, and makes it easier for users. The project is inexpensive, can be expanded with the library, and can be enhanced with items such as wireless upgrades and cellular phone applications.
