Project V - 35. Security Box with Fingerprint Sensor (Arduino Based)

Security Box with Fingerprint Sensor 

Security Box or trimmed with Arduino-based fingerprint security system. Brangkas can be opened only with the fingerprint of the person listed on the fingerprint sensor.

Hardware Requirement

}
}
}

How it Works

1. Connect the Arduino with Peripherals needed
2. Plug in the Power Source on the device
3. Compile and upload the script program above to your arduino

4. Before you use it,  you must register your fingerprint on the fingerprint sensor using enroll 

    program

5. Put the finger on the fingerprint key sensor will open automatically so that the opening can be 

    opened. As for locking back place finger on fingerprint.
