I did this a couple of months back and I've just realised I should have probably shared it on here. I had mentioned to Mossy about writing about it for Archive, but I don't think there's much more to say about it beyond this post:

It's far from polished, but it all works just fine. If you're feeling a bit 'tl;dr' about it, there's a video embedded if you scroll down.

Those Arduinos are really versatile beasts. Weren't higher end Arduinos used as MIDI controllers for those floppy drive music videos posted a while back?

In fact, I think Moppy will just use an Arduino Uno, as I've used here for the PS3 examples.
