Arduino Based Automatic Fingerprint Door-Lock

Fingerprint Sensor

Arduino IDE

Wire Cutter / Stripper, 5.25 " Overall Length

Scissor, Electrician

SG90 Micro-servo motor

Arduino Uno Rev3

<p >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.</p><h3 >Supplies:</h3><ul ><li >Arduino UNO</li></ul><ul ><li >Fingerprint sensor</li></ul><ul ><li >Servo Motor </li></ul><h3 >Step 1: Connections</h3><figure><img src=https://projects.arduinocontent.cc/1285bdb7-071a-4670-a08c-65d6e9a5e05c.png /><figcaption>Connections Diagram</figcaption></figure><p >Follow the diagram above for the Connections.
