Nifty little project involving a servo motor, fingerprint scanner, Adafruit neopixel ring, and of course an arduino.
Code that I used is available here [ Ссылка ]
Mostly a mashup of Adafruit fingerprint library stuff and Neopixel demos for good measure.

+other random stuff (plastic project enclosure, plywood for rigidly attaching the servo to the door lock). Obviously not all of this is essential, the Neopixel ring is just a cool way to display the program feedback, the servo wheel helped me attach the servo to the lock without permanently damaging it, and the proto shield just helped me stay organized with the wiring). Adafruit has great tutorials on most of the hardware I used.
