Relay Control and Solenoid Lock Operation: Upon successful fingerprint authentication, the Arduino board sends a signal to control the relay module, which in turn switches the power supply to the ...

Components Needed:** Arduino board (e.g. Arduino Uno) Adafruit R307 fingerprint sensor 20x4 LCD I2C module 6 solenoid locks Jumper wires Fingerprint Sensor Connections: Connect the fingerprint ...

The Fingerprint Door Lock (FPDL) using Arduino with SIM800L research is designed to improve the security and convenience of door access control by integrating fingerprint recognition with Arduino and ...

The SIM800L module ensures the encrypted transmission of data between the door lock system and users' mobile devices, providing secure and dependable communication. By integrating Arduino, fingerprint ...

In this Arduino based Solenoid door lock project we use a real Solenoid Door Lock and control it with RFID and Arduino. Here a Hall Effect sensor and a magnet are used to detect the door movement.
