What is Morse Code?
Morse Code is a system of sending messages that uses short and long sounds combined in various ways to represent letters, numbers, and characters.
How Morse Code was Used
An operater tapped out a message on a telegraph key. A telegraph key is a wire. The wire was a switch that opened and closed an electric circut, made by clicking sounds and was also written by dots and dashes on a paper.
How Morse Code was Developed
The International Morse Code was developed from the American Morse Code that was used by radio telegraphers. Today, only amateur and maritime radio operators still use this code regularly.
