Morse code is a communication system that encodes letters, numbers, and punctuation into standardized sequences of short signals (dots) and long signals (dashes). Press the letter/number to hear the signal (space to stop a sound), and read the guide to learn visually! This is a great way of secretly communicating secretly across the classroom, with flashlights into the sky, arranging books on a bookshelf to tell your past self to stay on Earth, and more!
