To be honest: Following Bertrand Russell “There is much pleasure in useless knowledge.” it was for me a no-sense project. Although the possibility using the MorseEbookReader by blind people might be a chance. But they have their
Braille Translator or can use another Arduino project: The
speech synthesizer.
The MorseEbookReader could be used by Ham operators who want to improve their
Morse reading capabilities. Up to 15 words per minute you can follow the signs by writing them on a sheet of paper. If the code gets quicker, MorseEbookReader (25 wpm), you have to translate it in your head. You do not hear the single dits and dahs. You hear whole characters or even words.
And that has to be trained.

And one last remark: Why use Morse code? It is still a very efficient way to talk to other people all over the world with a minimum of power and it is
faster than sms
