As a person without a car, I don’t need to carry keys around everywhere I go. Because of this, I’ve been locked out of my own house several times. It’s a pain to wait for someone with a key, so I thought I would do something about it.
This project is my way of solving this problem, while getting the chance to interface with an awesome fingerprint scanner (aka: FPS).
Also, this module isn’t restricted to just garage doors, for you can create different kinds of simple motorized locks to suit your needs.
Fingerprint scanner (and JST connector)
