    • Hello,
      Probably a too recent version of the Arduino IDE, specially if you are using Windows 7.
      Try with version 1.6 or 1.7

    • Hello Gael
      I have now tried the IDE 1.6.8 and 1.6.10 but without success. I still get the error messages. I am definitely doing something wrong. It does not komplitiert the MRLComm.ino code.
      Would love to continue the project because I now have the head ready and wanted to try it out.

    • Hi guys
      Found the error. Wrongly placed the mrl folder and so the Arduino IDE could not komplitieren. Small error with great effect
