You probably have seen or even used fingerprint scanners for security. Commercial versions of these biometric devices are becoming quite cheap, and accurate over 98%. However, it’s kind of cool to build your own door or garage lock with a fingerprint scanner with Arduino. It takes a few tries to get it right, as you have to train the program to learn. But once set, it usually works pretty well.
Although you can go pretty fancy with the items and casings, it’s best to keep it simple to start with. The video below shows the neat little scanner. You can try it on your own as a weekend project, once you have all the right parts.
The Instructables link has very thorough details about this project, including the code.
You can come up with your own idea about the fingerprint lock and create a new device that can be really useful. Maybe even start a Kickstarter campaign with it!
