This project presents a smart door access control system built around the BBC Micro:bit microcontroller. The system is designed to enhance home or office security by allowing access only to authorized individuals carrying an RFID magnetic card.

At the heart of the project is the RFID-RC522 module, which reads the unique identifier (UID) of any RFID card brought close to it. The Micro:bit processes this UID and checks it against a list of authorized cards stored in the system. If the UID matches a registered card, the door unlocks by rotating a servomotor, simulating the action of opening a door.

To improve user interaction, an I2C LCD display is used to show real-time feedback such as:

“Scan your card”

“Card refused”

This visual feedback makes the system user-friendly and helps in debugging and demonstrations.
