step4step:
i did't get any results.
What does that actually mean?
step4step:
Guess the distance between pot and controller/ servo is just to big ( resistance to high probably)
"Guess" and "probably" are not good words to use in electronics: that's why we have meters.
Have you measured the resistance of the wire?
Have you measured the voltage across far ends of the 5V and ground wires to and compared them to the actual voltage of the 5V pin to ground?
Have you measured the voltage on the Arduino end of the wiper with the pot turned fully to the high voltage side?
step4step:
I'll hook up the servo externally.
Don't forget the ground wire from the servo and its supply to the Arduino:
