In this repository you can find a variety of different sketches that will run on my MorseCard. If you're new to Morse code you can try out MorseCard-Easy.ino, a sketch which allows you to get acquainted with the Morse code signals. MultiStation.ino allows you to connect with other MorseCards via a speaker cable to send messages like a telegraph. Quiz.ino will give you a letter to signal out and check if you are correct.
You can check out the build instructions on Hackster. Fork this repository and create some sketches of your own!
The MorseCard has three buttons on it. These are labelled "Morse," "Lttr" (or letter), and "Space." The Morse button allows you to tap out the dots and dashes that compose characters. After you enter the code for a letter, tap the letter button to convert this letter into its textual representation. Then, tap the space button to add a space. Connect to another MorseCard via a speaker cable and the same message should appear on the screen of the connected device. This mode allows you to converse without having to worry about complicated timing.
This sketch is a small game that helps you learn Morse code. It will display a letter on-screen, and you have to enter the correct code for that letter with the Morse button. When you're finished, press the letter button to see if you're correct! If you don't happen to get it right, the MorseCard will tell you the correct symbol for that letter.
Multistation will simply read whatever Morse code is coming in from one of the pins on the ATtiny. This pin is connected both to the terminal block and the "Morse" button, meaning that you can connect your MorseCard to another MorseCard! In this sketch are a few pre-defined timing functions to figure out the spacing between letters and words. If the timing rate feels wrong you can try and tweak these yourself.
