Well i tried it again...
i observed something new. The new servo run the sweep example from 0 to 180 degrees and then started twitching. Thus i rotated the servo with my hands back and then again connected it to the arduino. And it again only goes from 0 to 180 degrees up but not back?
Do i have to add something to the normal code to get it working? Signal on pin9, vdc on 5V pin, GND on GND.

#include <Servo.h>
Servo myservo; // create servo object to control a servo
// a maximum of eight servo objects can be created
int pos = 180; // variable to store the servo position
void setup()
{
myservo.attach(9); // attaches the servo on pin 9 to the servo object
}
void loop()
{
for(pos = 0; pos < 180; pos += 1) // goes from 0 degrees to 180 degrees
{ // in steps of 1 degree
myservo.write(pos); // tell servo to go to position in variable 'pos'
delay(15); // waits 15ms for the servo to reach the position
}
for(pos = 180; pos>=1; pos-=1) // goes from 180 degrees to 0 degrees
{
myservo.write(pos); // tell servo to go to position in variable 'pos'
delay(15); // waits 15ms for the servo to reach the position
}
}
