@627117717.pr Ah, sorry to hear that you might be missing your deadline. On the other hand, I did have a pleasant surprise that, as a newbie in Rpi, and python, you are learning fast, in this a bit over ambitious project. As I said, I am a slow guys, still going slowly. I think there is 50% chance that I would digest Mario Gomez's difficult to understand code, and rewrite my own newbie friendly version.
