First, you need to know Morse code. If not use Google. Use the space bar to put in • , or — . Use the "Timer" at the top of the screen to put in dot or dash, 0.5 is dot, 1 is dash. after every letter, press "D" to decode each letter. press "B" to make a space, then press "D" to decode. •DISCLAIMER• DON'T USE A SPACE AND A LETTER IN THE SAME DECODING, OR ELSE YOU WILL GET THE FIRST LETTER. Also, if any of the letters are wrong, let me know, and tell me what they actually are in Morse code. I want to make this the best it can be.
