DIY Fingerprint Scanning Garage Door Opener

Nodcah wrote this awesome tutorial for a DIY fingerprint scanning garage door opener. via Instructables

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.

Part List:
Fingerprint scanner (and JST connector)
Serial LCD kit (w/ATmega328)
ATtiny85
PNP transistor
Buzzer
Speaker wire
3D printed case See step 9 for files
Copper tape
5V voltage regulator
9V battery
9V battery connector
SPDT limit switch

Tools: Soldering iron/solder
Electrical tape
Hook up wire/ jumpers
Wire cutter/stripper
Perfboard
Assorted resistors
Screws
Drill
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)

  1. One of your better tutorials of late, thanks. Reason number 101 to buy a 3D printer.
