/*Play a Morse Code message on the speaker
Rules of Morse Code:
- Dots are 1 'unit' of sound
- Dashes are 3 'units' of sound (3 times as long as a dot)
- Spaces between symbols within the same letter are 1 'unit' of silence
- Spaces between letters are 3 'units' of silence
- Spaces between words are 7 'units' of silence
