Build a Secure RFID Door Lock System with Arduino and Real-Time Access Logging

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

In a world where key-based locks are no longer sufficient, you'll assemble a complete RFID access system that grants entry only to authorized cards and silently logs every event with a precise timestamp on an SD card—giving you a professional-grade security log right on your workbench.

What You'll Build

With this kit, you'll build a functional door lock prototype that reads RFID cards and fobs, activates a solenoid lock, displays status on an OLED screen, and records every access attempt with date and time onto a microSD card. The system distinguishes authorized from unauthorized cards via LEDs and buzzer feedback.

What You'll Learn

• Interfacing MFRC522 RFID reader with Arduino and reading card UIDs
• Controlling a high-power solenoid lock via a relay and flyback diode
• Logging event data onto an SD card with RTC timestamps for real-world audit trails
• Designing a multi-component embedded system with status feedback on OLED and audio/visual alerts
