Open the garage door with a fingerprint sensor and Arduino

Fingerprint sensor lock and Arduino Mini

With an Arduino board you can do many things and thanks to its mini models, the world of possibilities and projects increases considerably. A good example of these possibilities we have in the project of the young Joebarteam which has used a small Arduino board to build a lock that opens with a fingerprint sensor.
The operation is the same as the operation of our mobile: we put our finger on a panel that is next to the door and the door unlocks. However, the application of this project goes beyond seeing how a lock is unlocked.

Smart lock with Arduino Mini is a cheap reality

Joebarteam has installed this lock on a garage door in such a way that with swiping your finger over a panel we can open and lift the garage door. And all powered by an Arduino Mini Pro board, a board with a very small size but with a lot of power.

The cost of the project is quite affordable, as The fingerprint sensor can be purchased for approximately 16 euros and the Arduino Mini Pro board does not usually cost more than 15 euros, being in total a very low price in relation to the same proprietary locks.

Joebarteam I have published the creation guide and construction in Instructables. A fairly long guide but one that is worth it since the result is positive. Of course, this project may undergo some alterations and changes. This would allow us to have the fingerprint sensor on one side and to be able to open the door without having to get out of the garage.

We could also change the fingerprint sensor for a remote control via bluetooth. Something that would allow us to open the door without having to get out of the car. All this thanks to Free Hardware and for a cheaper price than proprietary locks.
