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.
Step 1: Materials
Here is a list of almost all of the parts (It's a Sparkfun wishlist).
- Soldering iron/solder
- Electrical tape
- Hook up wire/ jumpers
- Wire cutter/stripper
- Assorted resistors
- 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)
