Morse Code is a method used in telecommunication to encode text characters as standardized sequences of two different signal durations, called dots and dashes or dits and dahs. Morse code is named after Samuel Morse, an inventor of the telegraph. (Wikipedia)

Is Morse Code Still Used Today?

The short answer is no.

Morse Code is still widely recognized, even if it is not as widely used as it once was. Morse code is still popular among amateur radio enthusiasts.

The US Navy and Coast Guard still use signal lamps to communicate via Morse Code.

Morse Code has also been used as an alternative form of communication for people with disabilities. There have been several cases where individuals have been able to use their eyelids to communicate in Morse Code by using a series of long and quick blinks to represent that dots and dashes.

It's also still seen as a fun option for encryption enthusiasts.
