Escape Room Security Terminal Puzzle Tutorial

In this video, I'll explain how to create a high tech "Security Terminal" escape room puzzle, using a Unity application to provide a front-end interface, and a Wemos D1 Mini (although you could alternatively use an Arduino with Wi-Fi/ethernet shield or ESP32) to control hardware via a relay module.

Players encounter a terminal console (a desktop or laptop PC which is running a custom Unity application) which prompts them to enter a security override password. Entering the correct password causes the app to send a message to an MQTT broker (which can either be running on the same PC as the terminal app, or a PC in the ER control room etc.). The Wemos D1 mini is also subscribed to this broker and, when it receives the message, deactivates a maglock to release the door, and triggers a strip of Neopixel LED lights to flash green. Entering an incorrect password re-activates the lock and secures the door again. This could be used in a wide variety of escape room themes, from spies to space stations.
