So, I have 8 servos that I want to drive with my Arduino. I know I shouldn't connect all the servos to the GND and +5v of Arduino. Somebody told me that servos when working pull about 2 amps each Is this correct? How should I hook an external battery with Arduino to my servos? I am told that I can hook up DC jack into Arduino, an external batteries GND to Arduino's GND, and the external batteries + to +5v on Arduino. Is this correct? Please help me out here.

Yep that's right. Have a look at my pic below, and go and read DuaneB's work, starting here. He has some test results for current draw.

Consider the daffodil. And while you're doing that, I'll be over here, looking through your stuff.   8)

Thanks Zimbo for the tremendous help. I'm enjoying the website you linked to your post, it's very helpful. What I'm making is a 4 legged spider! (I really hope it works :)
Zoomkat, makes perfect sense. Thank you as well.

That's Jimbo  8), but you're welcome all the same.

Yep DuaneB seems to be the go-to-guy for servo know-how.
