Morse Code Project | |
This code will loop through a string of characters and convert these to morse code. But first you have to get the password to start the morse code seation. | |
It will blink two LED lights and play audio on a speaker. | |

Pause between elements = Dot length | |
(pause between dots and dashes within the character) | |
Pause between characters = Dot length x 3 | |
Pause between words = Dot length x 7 | |
