This is an implementation of an adapter to let you run a NeXT keyboard over USB.

A great deal of credit goes to Limor Fried, who wrote a tutorial that I used heavily in my early versions of this code. Parts of that code are reused here under the BSD license.

I used this as a way to learn Arduino, and embedded software work, and hardware reverse engineering. I don't think this code is especially well-structured or thought out!

Requires arduino-cli. Use make upload to upload to an Arduino Nano.

Looks for the arduino at /dev/arduino, which assumes that udev has a rule like this:

SUBSYSTEM=="tty", ACTION=="add", ATTRS{idVendor}=="2341", ATTRS{idProduct}=="8037", SYMLINK+="arduino"

(that's in my /etc/udev/rules.d/10-local.rules file).
