I hadn't seen this before, but the author of the myFocuser arduino project also has a Sky Quality Meter project which uses all the same components as described here in Peter's project.
His code for the Cloud Sensor side of things is pretty rudimentary compared with Peter's.
However, the project as a whole adds a few possibilities in the ASCOM driver side of things which may make it a bit easier to use than pushing files around.
