John Park’s Mystery Box: The Freefall Deck with MakeCode @adafruit @johnedgarpark #adafruit

Perfect for escape rooms, magic tricks, and other mysterious events — this seemingly innocuous, sealed deck of cards contains a secret. When the puzzle is solved, the deck is thrown in the air, tossed to a friend, or dropped a short distance. Freefall is detected by the Circuit Playground embedded within, and it beeps a secret Morse code message.
