⚙️ Working Principle

1. Power ON the system.
2. LCD displays "Scan RFID Card".
3. EM-18 RFID reader reads the RFID card.
4. LPC2129 compares the scanned RFID with the stored authorized ID.
5. If the card is valid:
   • LCD displays Access Granted
   • DC motor starts (Engine ON)
6. If the card is invalid:
   • LCD displays Access Denied
   • Engine remains locked
   • GSM module sends an SMS alert to the owner
