This project is an RFID-based smart lock system built using Arduino. It allows secure access control by verifying RFID card UIDs and controlling a servo motor to lock or unlock a mechanism. The system also provides visual feedback using LEDs to indicate whether access is granted or denied.

The project is developed by Mayank Biswas as part of a practical electronics and embedded systems implementation. It focuses on creating a low-cost, reliable, and beginner-friendly security solution.

In the future, the system can be enhanced with features like multiple user support, IoT connectivity, display integration, and additional authentication methods such as a keypad or mobile app control.

This project uses AI

I utilized AI tools for idea generation, coding assistance, and enhancing the project write-up. However, I understood, implemented, and tested everything myself; this project reflects my own work and learning.I used AI tools to help with ideas, coding support, and improving the project write-up.

In this project, I designed and built an RFID-based smart lock system using Arduino. The main objective was to create a simple, low-cost, and reliable access control system. I started by connecting the MFRC522 RFID module with the Arduino and testing basic card detection. After successfully reading RFID card UIDs, I implemented logic to compare the scanned UID with a predefined authorized UID.

Next, I integrated a servo motor to act as the locking mechanism. The servo rotates to unlock when a valid card is scanned and returns to the locked position after a short delay. To improve user feedback, I added two LEDs: a green LED to indicate access granted and a red LED for access denied.

During development, I encountered issues, including repeated card scanning and unstable behavior. I solved this by adding a timing-based debounce system to prevent multiple rapid scans. I also removed unnecessary components like the ultrasonic sensor to simplify the system and improve performance.

Throughout the project, I tested the system multiple times to ensure accuracy and reliability. This project helped me gain practical experience in Arduino programming, RFID technology, and hardware integration. It also improved my problem-solving skills and understanding of real-world embedded systems.
