user16611: I'm a newbie so forgive my ignorance.
I'am using the Morse code translator to light up the LED which is fine but after it has processed the sentence it turns off. How can I get it to loop the sentence continuously. 
Thanks

user13432: I guess this is the sketch you are using. It reads characters from Serial and translates them to Morse code. 
What you need to do to make it loop a sentence is, 1) read a sentence into a buffer, 2) loop though the buffer and translate to Morse code.
