Telegraph made using 2 arduinos and simple pushbuttons

     Each arduino functions idependently reading input from each of its three buttons.  One button represents a dot, another a dash, and a final represents a space.  If the space button is pressed multiple times in succesion it will first denote a letter, then a word, then the entire message.

    Using serial connections the final message is sent to the other arduino where it is then printed out to the monitor.
