Sorry the last post was incomplete: problem is that the serial changes (from the cotrrect choosen port com3 to com1) as soon as I connect some actor/sensor to the arduino. This occured first time when I unplugged the arduino while running! before everything was fine.
perhaps in the intern software of Arduino something was shot down?
If anybody has experience with this I would be glad to hear about.
