A Morse code translator is a useful tool that converts plain text into Morse code and decodes it back, allowing users to understand messages made of dots and dashes. It was originally developed in the 19th century by Samuel Morse and Alfred Vail for long-distance communication through telegraph systems. Today, it is widely used in online tools and apps for learning, experimentation, and educational purposes. In simple terms, learning what is morse code helps us understand how early communication systems evolved into modern digital encoding methods.
