ahhhhhhhhhhhh - I created a door/window sensor some weeks ago - but I couldn't make it run to fire an interrupt on pin change (INT0 and INT1 are used to connect external magnetic sensors) - today I decided to work on this issue again and found this topic at the forum - so I downgraded my arduino IDE by downloading v1.6.8 from arduino.cc today - compiled my code again - falshed it - and voilà - it works
That is really frustrating by wasting that many hours of time only by inconsistancy with compiler/board definitions.
Is there any need to update to newer arduino-IDE - otherwise I would recommend to general stick to one version ...
