Morse code is a type of code that is used to send telegraphic information using rhythm. Morse code uses dots and dashes to show the alphabet letters, numbers, punctuation and special characters of a given message. When messages are sent through Morse code, dots are short clicks and dashes are longer clicks.
Morse code is named after Samuel Morse, who helped invent it. It is not used as much today as it was in the 19th and 20th centuries, because there are now other types of technology that are easier to use to communicate. However, some people still use Morse code to communicate on amateur radios, which are also called ham radios. Many people do this as a hobby.
