"Crown Jewels" Escape Room Puzzle Tutorial using Multiple Colour Sensors

Here's a tutorial video explaining how to build your own escape room puzzle that uses multiple color sensors to detect the placement of various coloured "gems". Each time a gem is correctly placed, a corresponding LED lights up the matching color. When all gems have been correctly placed, a relay is activated which releases a maglock. It uses an ESP32 (although an Arduino, or any other microprocessor, will work just as well), a TCA9648A I2C Multiplexer, 5x TCS34725 colour sensors, PL9823 programmable LEDs, a relay module, and an electromagnetic lock. Full wiring and coding is illustrated in the video.
