Arduino RFID Door Lock System with LCD Screen Set

Description

Introduction to Arduino RFID Door Lock Kit

The Arduino RFID Door Lock System with LCD Screen Set is a practical kit for building secure RFID-based access control systems. It combines an Arduino Uno R3, RC522 RFID reader, 16×2 I2C LCD display, 12V solenoid lock, and relay module to create a complete smart door locking solution. Moreover, the kit helps users learn RFID technology, home automation, and embedded programming through hands-on projects. It supports Arduino, ESP32, IoT applications, and other embedded platforms. Therefore, it is suitable for students, hobbyists, educators, engineers, and anyone interested in smart security systems.

How the RFID Door Lock System Works

The RFID Door Lock System scans an RFID card or tag using the RC522 RFID reader operating at 13.56 MHz. The Arduino Uno R3 checks the scanned UID against the authorized IDs stored in the EEPROM memory. If the card is valid, the controller activates the 5V relay module, which powers the 12V solenoid lock and unlocks the door. At the same time, the 16×2 I2C LCD display shows the current system status, such as “Access Granted” or “Access Denied.” As a result, users can create a reliable electronic door security system with simple hardware and programming.
