Morse Code

Morse code (morse), also known as Morse cipher, is an intermittent signal code that expresses different English letters, numbers and punctuation marks through different arrangements. It was invented in 1837 and is an early form of digital communication. Different from modern digital communication, Morse code only uses binary codes in two states of zero and one. Its codes include five types: the short dot signal "·", the long signal "—" that lasts for a certain period of time, the pause between dots and dashes, the medium pause between each word, and the long pause between sentences.
