The "Decanting Problem" Escape Room Tech Puzzle

This is a video tutorial explaining how to create an electronic version of the "decanting problem" (also sometimed called a "water-pouring problem": https://en.wikipedia.org/wiki/Water_p..., which is a great puzzle for use in an escape room.

It uses different length WS2812B ("Neopixel") programmable LED strips to represent containers of differing capacities, and an audio cable to represent a "filling loop" which must be connected to transfer liquid between containers. The code is run by an Arduino UNO, which releases a maglock when the chosen target value is attained in one of the containers.
