print statements
DrAzzy:
So have you checked via print statements that the point where the servo position is set is really getting run, and that your code is setting it to the position you think you are?
Could you give me an example how you mean that? I just got the "Serial.print" commands wich i checked...
DrAzzy:
jitter and electrical noise are not the same. Jitter is a correct signal, but inconsistent timing, as opposed to spikes that shouldn't be there at all (for example, the starting and stopping of inductive loads can put spikes onto the power supply rail, sometimes large enough to reset or crash other things powered from it - though it sounds like this isn't happening here, since you report that it doesn't stop printing debug output).
Ok, i think i make a video to this, i can't explain here what really happens..

When i connect the Wall Adapter it doesn't start, only after booting the Arduino, so it has to come from the signal..?!
