An Arduino converts Morse code characters tapped at the key into keystrokes over USB. As ... [kodera2t] took things into the digital age with Stand-alone Tiny Morse code encoder/decoder.

byte enc1oldPins = 0; // will hold state of pins last time encoder was read byte enc2oldPins = 0; byte enc1newPins = 0; // will hold new encoder pin reading, to be compared with last time's pin states ...

This project uses two Arduino to communicate with each other using light by means of Morse Code. As a more advanced project, it has some complex array usage and investigates converting switch inputs ...

An Arduino converts Morse code characters tapped at the key into keystrokes over USB. As [voxnulla] knows, when butterflies aren’t available , real programmers drive vim with a Morse key!
