Morse Code Communicator

It is a fact that, if conditions are so bad that all other forms of communication fail, Morse code transmissions can often get through. It was the first form of radio communication, and in these days of space satellites, you can still hear amateur radio operators talking to each other around the world in Morse code – just for the sheer pleasure of it.
This project will help you learn Morse code and communicate with others who know this special ‘language’.
