The programming is almost done (and VERY messy, I'm going to have to clean it up), and I've began testing with an Arduino Mega 2560.

Some bugs I've noted:

• 90% of the time, when you morse a character incorrectly, it will print "36".
• After a few characters are sent, the morsing speed begins changing erratically.
• Worst of all, every half a second or so, a "DIT"/"DOT" is sent without any action taken by the user.

Hopefully, they are all minor problems. I believe the first problem lies here:

void printPunctuation()
{
  byte pMark = '#'; // Just in case nothing matches
  if (myNum == 71)
    pMark = ':';
  if (myNum == 76)
    pMark = ',';
  if (myNum == 84)
    pMark = '!';
  if (myNum == 94)
    pMark = '-';
  if (myNum == 101)
    pMark = '@';
  if (myNum == 106)
    pMark = '.';
  if (myNum == 115)
    pMark = '?';
  Serial.print(pMark);
}

The second and third issues are more of a mystery, and I need to make all the wait times for sending morse proportional, but we're getting there :)
