Morse Code

Morse code is a special way to send messages. It uses short signals called dots and long signals called dashes. Each letter of the alphabet has its own pattern of dots and dashes. Morse code was invented in the 1830s by Samuel Morse. People used to send messages over long distances this way.

How It Works

In Morse code, the letter A is a dot and a dash. The letter B is a dash and three dots. The most famous Morse code message is SOS, which means 'help!' SOS is three dots, three dashes, and three dots. It is easy to remember and easy to tap out.

Sending Messages

Long ago, people sent Morse code over wires using a device called a telegraph. Tapping a key would send a click to the other end. Later, ships used Morse code with radios and lights. Pilots and soldiers used it during big wars. Today, some people still use Morse code as a hobby.

Fun Facts
