-A dot is 1 unit, so in the case of this app, you set the Dot Time.
-A dash is 3 units
-Parts of a letter have a 1 unit pause
-Between two letters in a word is a 3 unit pause
-A space is a 7 unit pause
When the Morse code is played, dashes and dots are represented through periods where the light is turned off and pauses are periods where the light is on.
As of version 1.02, the characters A-Z and 0-9 are supported. Letters are not case sensitive.
