Hello, I am having some troubles getting going with using servos. I have been running the included sweep code from Arduino 0015 on a duemilanove. I am using a Futaba FP-S148 servo powered separately on 6V. The control wire from the servo is plugged into digital port 9 on the Arduino board. As soon as the servo is plugged into the board, it immediately turns as far as it can clockwise and attempts to hold the farthest clockwise position until it is unplugged. A different servo of the same model gives the same result; as does if the code is changed to port 10 and servo is plugged in 10. Anyone have any thoughts on potential causes of the problem? Thanks
Do you have the servo ground wire connected to Arduino Ground?
I do now & it works. Thanks for the help mem
