What other interesting examples of codes from history or the modern-day (digital or non-digital) can you find to inspire or support a lesson about encoding and decoding messages?

Morse code is a communication system developed by Samuel FB Morse, which uses strings of dots and dashes to convey encrypted messages. Although originally invented for telegraph communication, Morse code is still used today by amateur radio broadcasters, and it is also useful in transmitting emergency signals in times of danger. Learning Morse code is not difficult, but it requires the same study and effort as learning a foreign language. Once you’ve mastered the basic symbols, you can start writing and translating your own messages.
