The International Morse Code is a system of dots and dashes that can be used to send messages
by a flash lamp, telegraph key, or other rhythmic device such as a tapping finger. As a
telegraph key is moved up and down, it makes or breaks an electric circuit and transmits a
signal as a series of electric pulses. The telegraph was invented by Samuel Morse in 1837. In
the International Morse Code, each letter or number is represented by a combination of dashes
and dots. A famous Morse Code signal signifies distress: dot dot dot dash dash dash dot dot dot (SOS).
