Fingerprint Door Lock System

An Arduino-based fingerprint door lock system is a security device that allows access to a building only after the user's fingerprint has been recognized. The system is built around an Arduino board, a fingerprint sensor.

The uniqueness of fingerprints is what makes them an ideal way to secure access to a building or system. Fingerprint sensors capture the unique pattern of ridges and valleys on each individual's fingertips, which cannot be replicated or duplicated.

The captured image of the fingerprint is processed and saved as a binary code in the memory of the fingerprint sensor. This code is then compared to the fingerprints presented by users, and if a match is found, access is granted.
