    this is amazing, i have been trying to do the same but i couldn’t manage to get more than 9 sensors to work at the same time, anyways thanks a lot for the schematics and codes, great work

  1. Excellent post however , I was wondering if you could write a litte more on this topic? I’d be very grateful if you could elaborate a little bit further. Thanks!
