Morse code
Introduction: The telegraph was first invented by Morse in the United States in 1844, so it is also called Morse code.
It consists of two basic signals and different intervals: short dot signal "*", read "" (Di); keep one
Long signal "-" at fixed time, read "Answer" (Da).
Interval time: tick, 1t; answer, 3t; tick, 1t; letter, 3t; word, 5t (customize a unit time t).
Note:*Indicates a short signal,-Means long signal
