In this video, I'll explain how I created a physical electronic "deduction board" logic puzzle game inspired by games such as Cluedo (Clue) and The Traitors, in which players must eliminate suspects using logical deduction until only one valid solution remains.
It uses an Arduino Nano, 15x arcade buttons, a DY-SV5W MP3 player module, 3x PCF8574 port expanders to read the button inputs, and 3x TPIC6B595 power shift registers to drive the LED lamps.
I also added a relay that can deactivate a maglock when the puzzle is solved, making it suitable for use in escape rooms, for example.
