The Morse code is a way of transmitting messages with short and long light or sound signals. It works by translating letters into sequences of short and long signals of light (or sound). A long signal is called a dash, and a short signal is called a dot. The first letter in the alphabet, A, is translated as Morse code as .- and the letter Z is translated as --..
It was originated in 1838 by Samuel Morse. Morse code can be translated into text messages so it has been utilized by the military, law enforcement, amateur radio operators, and ham radio operators. To use morse code, one would use a dot which is represented by a “.” symbol, or a dash is represented by a “-“.
