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)
Serial LCD kit (w/ATmega328)
3D printed case See step 9 for files
5V voltage regulator
9V battery connector
SPDT limit switch
Tools: Soldering iron/solder
Hook up wire/ jumpers
A few LEDs for testing
5V FTDI board
Hot glue gun
Access to a 3D printer
Optional: IC holder (8 pin for ATtiny and 28 pin for ATmega)
Optional: Another Arduino board/10uF capacitor (see step 5 for details)
