servos connected directly to the arduino?
As long as the servo doesn't pull more current than the powersupply/voltage regulator/battery pack can supply, you won't have any problems driving a servo directly from pretty any* microcontroller.
*NOTE: I say any with a note, because, I don't know of any micro that would have a problem driving a servo directly. Just because I don't know of one, doesn't mean there isn't one out there that can not drive a servo directly. It probably would not be very useful to robotics.
i made the incorrect that servos and motors operated similarly....now I understand, thanks.
