my servo is going crazy

Hi. I purchased brand new servo named towerpro mg16r and I have some problems with it. I loaded sweep example to my arduino uno and that is what happened: http://www.youtube.com/watch?v=HFGyABWMgf4&feature=youtu.be Any solutions?

Perhaps you can describe what happens to save me the trouble of loading a youtube video?

A common problem is that people try to power the servo from the Arduino. A servo needs to have its own power supply - the Arduino can't supply enough current.

Hi , just viewed your movie. As Robin2 said you cannot power a servo from the 5V supply on the arduino. It will need its own, probably rated at 1/2 to 1 Amp per servo, they use power in fits and starts depending on where they are and have to go. The arduino cannot supply the current peaks needed by the servo.

And this is, by the way, in spite of the tutorial on this very site telling you to do exactly that.

Zoomkat’s well-known schematic is attached.

We had better laminate that schematic file, we'll wear it out if we don't. Tom... :)
