Wireless communication is something that we use every day. But years ago, Morse Code was used to send messages. This communication was based on a series of dots and dashes that stood for individual letters and numbers sent by telegraph on radio channels. It was sent by whistle, buzzer, tapping, flags, and many other ways! Using a buzzer and a button switch, campers recreated the original Morse code and sent each other secret messages to decipher.
