Yes, only run Hypercon, in your case on the windows pc. You should really create the .json file yourself, there lots of info that others will be guessing on. basically for your .json the "Type" well be "adalight", the "Output" well LIKELY be "/dev/ttyUSB0" and the "Eternal" tab setting will have the Kodi checker enabled and the IP set to the Kodi PC's IP.
Have you programed your arduino with the developers preferred arduino sketch from (https://github.com/hyperion-pr…firmware/arduino/adalight )? It has lots of comments in the sketch for proper configuration. And there is always the [WIKI]HyperCon Guide[/WIKI].
Hope it's helpful.
