Description: Arduino code for a homemade steno keyboard. There are two files. "steno_keyboard.ino" was for the first board which used an Arduino Mega and a separate port pin for each of the 23 keys. "mux_steno.ino" is for the second board which used an Arduino Micro and multiplexed the 23 keys with 10 pins and 23 diodes.
