Arduino Based Automatic Fingerprint Door-Lock

This is an arduino based fingerprint doorlock prototype. In this Model, when we put our finger on the sensor the program takes an image of it and tallies it with the enrolled fingerprints. If the finger is recognized then the door automatically opens for a specific time we declared in the code and after that it close on its own.

Supplies:

• Arduino UNO

• Fingerprint sensor

• Servo Motor

Step 1: Connections

Follow the diagram above for the Connections. You can cut the blue and green wires of the fingerprint sensor as they are not needed. I have also done the connections as per the diagram.

Step 2: Code

We will need to upload 2 codes.

• First: Open Arduino IDE and go to File>Examples>Adafruit Fingerprint Library>enroll. Upload the opened code into the Arduino. Now open the Serial Monitor and follow as it says.

• Now Uploaded my code I attached below into the Arduino.

Step 3: House

Follow the steps in the video Above. I used a metal piece to make the house stand on a base, you can use anything.

Step 4: Its Ready!
