Escape Room Puzzle Tutorial - "Symbol Wheels"

Learn how to create an escape room puzzle in which players must rotate a set of stone discs so that all the symbols along their touching edges match. The position of each disc is monitored by an Arduino and, when the puzzle is correctly solved, a relay is activated, releasing a key from a maglock.
I'll illustrate how I used Inkscape to design and layout the symbols on the stone discs, which I cut on a CNC router (though you could easily create these using hand tools and paint the symbols on). I used Minizinc to model the puzzle logic and ensure that only one unique solution existed, and the Arduino IDE to program the puzzle controller.
