Hello!
Just before the site got switched, that part had an amazingly well written write-up documenting the methods behind how to connect it to an Arduino, (it showed a Redboard). Including how to wire it and program it and the Redboard. Further it also showed how to connect the matching receiver. Now it does not. The “Good AVR tutorial” has gone dark. The other one was not at home. The GitHub page was of course. And that hookup page had the demo code I was originally concerned with in a different one.
