The morse code alphabet isn't really an alphabet but a system of dots and dashes that represent letters and numbers, invented by Samuel Morse for the telegraph. Each character is a unique sequence of signals, with short dots and longer dashes separated by pauses, making it possible to transmit messages via sound, light, or even touch across distances.
