"Magical" interactions in escape rooms use a variety of electronic sensors to detect and trigger effects based on the players' actions. Many escape room puzzles use magnetic or RFID sensors to determine if, or what, object has been placed in a particular spot. But it's not always possible to attach a magnet or RFID tag to every object - and certainly not to conceal it.
In this video, I'll present an alternative sensor - an inductive sensor that detects the presence of any nearby metallic object. I'll show you the wiring required to use one or more of these sensors, so that players are required to place a number of metal artefacts in particular spots in order to activate a relay and unlock a maglock.
This tutorial requires only a handful of easily-sourced electronic components and, unusually for me, no Arduino or ESP32!
