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.
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)
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

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