Using an Arduino Uno, a servo, a few led's and a Sparkfun FPS scanner, you can create a customized lock box that recognizes your unique finger print.
The materials list is below and schematic is in the repository. Once the library in the repo is added to your Arduino IDE, upload the example sketch "FPS Enroll". Once uploaded to the board and the FPS scanner is connected, open the serial monitorand follow the serial.Print commonads. They will prompt you to press down the same finger 3 consecutive time. Once the enroll is successful, you can upload the "FPS Id" sketch to your board and watch the magic happen. Control anything from it really.
Have fun, let me know if you found this repo helpful and share with me (and the world) what you make.
