Low cost fingerprint lock door

Technozone fingerprint lock door

This project was created due to need of providing access to school's science club for all permitted members. In the future it will be expanded to work with backend server hosted on Raspberry PI which would contain logs providing informations about each lock opening.

This is MVP.
