Creating a "Biometric Hand Scanner" Real-Life Escape Room Game Puzzle

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.

Extremely clever chap! Please consider making a gps tracker with phone app, love anything gps related! It’s great how you comprehensively take us through the code in great detail, am really trying to learn this stuff! Really appreciate it!

Hi Ian, thanks for the comment - did you already see kzbin.info/www/bejne/aYivh2mAgLaBgpo ?

[@iantcroft]

@@PlayfulTechnology Yes I saw that one, that’s why I was asking for more like it! Thanks.

[@TechEX507]

Genius! Thank you!

[@GearClinkz]

Amazing work!

Just a minor correction: "what we'll do is print out the IP address that we received from our local DNS server". It's a DHCP server that assigns IP addresses, while DNS is translating an IP address to a hostname.(even when going to www.youtube.com, that name gets translated to an IP address).

You should post the app on the app store and sell the release device

How to activate onTouch function?

Hey there, is there anyway we could get in touch for partnership? Let me know!
