#Morse code Hello world with red LED
#The below info. is copied from Wikipedia
#https://en.wikipedia.org/wiki/Morse_code
#The dot duration is the basic unit of time measurement in code transmission.
#The duration of a dash is three times the duration of a dot.
#Each dot or dash is followed by a short silence, equal to the dot duration.
#The letters of a word are separated by a space equal to three dots (one dash)
#and the words are separated by a space equal to seven dots
