So I have done a little more work on this. You may also notice that v2.2 was skipped. This is because it is mostly minor fixes. In this version there are more comments, and I added a few new commands.
The new commands are:

• /rand

• This command will generate a random message of 4 blocks of 5 letters each.
• It will also send to the terminal what the new message is.
• This is great for practice without knowing what the message is. Just send /rand and then look at the light. When it is done look at the terminal and see if you were right.

• These commands will hold the light in the on or off position.
• Great for a desk lamp. Just hook it up with a bluetooth module and when your not using the morse code just tell the light to stay on.
• Also good for remote controlling your light

• This will just display what the current message is stored on the arduino.

• This will add more to the end of the message.

I have more plans for this project to evolve but so far I am taking a break and focusing on other projects.

I am having a lot of fun with this project. In this update I added the ability to use prowords. But what are prowords? Prowords are symbols and letters with special meanings, they are a combination of letters into one letter. In morse code [AAA] together is Full Stop or Period, or [IMI] is Say Again. The list goes on and on. Basically by adding letters together you will create prowords. In this program to send a proword enclose the letters in square brackets [] so the program knows its a proword and not just each letter on its own.
Example message
“HELLO WORLD[AAA] HOW ARE YOU[INT]” would be
“HELLO WORLD. HOW ARE YOU?”
The [AAA] would be morsed as .-.-.- instead of .-/.-/.-
The [INT] would be morsed as ..-.- instead of ../-./-

Another little thing I added was a delay after the message to show that the message was over. Now there is no need to add a space at the end of the message to do this.

So I made a few changes to my previous Morse Code project. I added the option to send a message via serial. I am still waiting on my bluetooth module so I can send a message from my phone.

Syntax for the serial commands.
<message>
/wpm <speed>
/start
/stop
/restart
