I recently bought 6 servos from here: http://robokits.co.in/shop/index.php?main_page=product_info&cPath=2_5&products_id=187 .
It says to be Exact replacement for Futaba S3003 and Hitec HS-311.
In most of the website and the official arduino page I read that u simply can run one from an arduino,but in my case it didn't :-(
I tingered around with the circuit and supplying +5V from a seperate battery with its gnd connected to arduino it worked.
So I was wondering
1) Do we need to supply seperate +5V to servo's for it to work ?
2)Did it work in your case by simply hooking the 3 wires DIRECTLY with arduino?
3) What in case I need to power multiple servos(in addition to the arduino)Won't that be a lot of batteries?
Also I was wondering if an arduino provides more sinking current at its pins compared to lets say a bootloaded clone?
