Pretty much what it says on the tin. Connect to a USB port and it shows up as a keyboard. Use the key to toggle Morse code characters.
What Works : It sends characters through the USB port and beeps out dashes and dots.
What needs Fixing ( ) :
-Have a potentiometer that controls the input speed rate, or just switches to toggle slow, medium and fast
- add in a little more intelligent processing of Morse recognition
- add in a Shift signal to toggle between upper and lower case
- replace the DigiSpark with an ESP8266 to allow it to send and receive tweets
I don't recall where I found the original code, but there are plenty of examples out there.
