🔐 RFID Door Access System using Arduino
Smart Lock DIY Project | Secure Access Control
The RFID Door Access System using Arduino is a smart security project that allows authorized access using RFID cards or key tags. This system replaces traditional keys with contactless authentication, making it ideal for homes, offices, labs, and institutions. When a valid RFID card is scanned, the door unlocks automatically using a 12V solenoid lock, providing a modern and secure access control solution.
🚀 Key Features
🔑 RFID-Based Authentication – Access only with authorized RFID cards or key tags
🔐 Automatic Door Lock/Unlock – Controlled via relay & solenoid lock
📟 LCD Display Feedback – Shows access status and user prompts
⚡ Fast & Reliable Operation – Instant response on card scan
🧠 Arduino Powered Control – Easy to modify and expand
🏠 Perfect for Smart Security – Ideal for doors, lockers, and restricted areas
🧪 Beginner-Friendly DIY Kit – Simple wiring and coding
⚙️ How It Works
1️⃣ The RFID RC522 module scans the RFID card or key tag.
2️⃣ The card’s unique ID is compared with stored authorized IDs in Arduino.
3️⃣ If the card is valid, the Arduino activates the 5V relay module.
4️⃣ The relay powers the 12V solenoid door lock, unlocking the door.
5️⃣ The 16×2 LCD shows messages like “Access Granted” or “Access Denied”.
6️⃣ After a delay, the door automatically locks again for safety.
