Smart Door lock system with fingerprint using ESP32

In this project, we have developed a smart door lock system using a fingerprint sensor to open and close the door. We used ESP32 microcontroller and fingerprint sensor, L293D driver IC to drive the DC gear motor and the motor is coupled with the door lock. When the fingerprint match than only the door open or close. Who has authorized person only can open the door If any unauthorized person trying to open the door means they can’t open the door because the fingerprint sensor never accepts the fingerprint there is no response from the microcontroller side.
