GoPiGo servo does not stop spinning

I am trying to put together my first gopigo. I tried connecting the servo to the gopigo board yesterday. As soon as I power up the gopigo, the servo starts to spin all the way to one side. and it makes a sound as if it is trying to keep spinning. I powered down and spun the servo to the other end; but it again spins back and tries to keep going.
Could my servo be bad or is this something wrong with my gopigo board?

Hi Jose, the servo will start at a zero position. It will try to reset itself on power up. Your best bet is to remove the servo from the GoPiGo, let it set itself, and then reattach the servo. You might also run the demo program and set the value to 0 or 180, and then mount the servo.
