“Ever wanted a box that opens in a super cool way? We thought it would be fun to create a box that can be unlocked using the correct fingerprint! If we had more time, we would make the box more secure. In the mean time, we have learned a lot and had a lot of fun.
We found several tutorials online that inspired us to make this awesome project:
How to Set Up Fingerprint Sensor With Arduino
Techatronic Arduino fingerprint security lock
DIY Fingerprint Door lock System
Although this project is recommended for the beginner to intermediate level, we personally found several parts of it very challenging, and hope this Instructable will help others have an easier time than we did.
