Build an electronic door lock that can be controlled using fingerprint recognition on your Android phone

Build a biometric-controlled door lock with NodeMCU

Impress your friends and tighten up security using this neat biometric-controlled door lock project by Instructables user coderscafe. It uses an interesting chain of technology that ends with an electric door strike that's controlled by fingerprint access on an Android phone. 

The Android app is created using the modular environment in the Kodular platform, which sends data through the Firebase platform - which then communicates to a WiFi-enabled Arduino-compatible board that takes care of the electronic door lock. Check out the video below for a quick demonstration:

Even if you're not interested in controlling door locks, the system described is a useful learning tool and gives you the framework for you to control other devices from an Android phone. 

To learn more, please visit the project's Instructables page. And if you're interested in making your own version - PMD Way has you covered with NodeMCU boards, electric door locks, relay modules and more.
