Morse code translator

Morse code represents each letter as a sequence of short and long signals — dots and dashes. E is a single dot, T a single dash, and SOS is three dots, three dashes, three dots. Letters are separated by a space and words by a slash. This translator uses the ITU international alphabet, including digits and punctuation.

The timing is the part people miss. A dash lasts three dot-lengths, the gap inside a letter is one, between letters three and between words seven. Samuel Morse and Alfred Vail assigned the shortest codes to the commonest English letters, which they estimated by counting the type in a printer’s case — which is why E is one dot and Q is four symbols.
