In this video tutorial, I explain how to use Unity to create a fake "Biometric Hand Scanner" Android app for use in a high-tech escape room puzzle. Even though the app doesn't really scan your hand, pressing the fingerprints in the correct sequence really does open a door, just like in a futuristic sci-fi movie!
The door is secured by a maglock, controlled by a ESP8266-powered Wemos D1 Mini. When a player presses their fingerprints in the correct order, the Unity app sends a wireless trigger to a webserver running on the Wemos, which triggers a relay and cuts power to the door lock.

Components Used
