Thing #3 Did my name (tom marquette) in blinking mores code. Changed dots to delay 500, dashes at 1500 delays. Delays between letters are 1750. The Delay at end of loop is 5000. Delays between a dash or a dot are 250.
I am only able to count the total number of blinks (24) I lose track of the different between dot and dash very easily. It's hard to judge the time separating the end of a character string of blinks. My friend reminded me that he learned mores code by the sound of the dots and dashes. I'm thinking a single flashing light is just too hard to keep track of length of time.
What I think I am running into is the serial nature of the telegraph. In 1837 you had to push everything down one wire. The approach I'm going to try is sending dot signals to a blue LED, dashes to a red LED and spaces to a green LED. Well that's the plan ,,,, at least.
A possible project would be using a second Arduino with a photo sensor to measure the blinks and output the letters. The Arduino would do a way better job of noting the passage of time.
