im new to arduino and electronics in general but im making a very simple arduino robot. so far its all good but im a bit stumped as to what to use as a power source.
OOPS pressed enter by acident :P....
im using two continuous rotation servos and one normal servo. the board itself will be powered using a 9v batery... any sugestions on how i should drive the servos as i am aware the poer suplied from the arduino itself will not be sufficient.
what i use is a rc hobby receiver battery pack. its what servos are designed to be run off of. or if you dont have a hobby store nearby, 4 1.2v rechargeable batteries will work just as well. check the servo specs before using 4 alkaline's tho
but 4 alkaline's would be enough to power all 3 servos?
Use a plug wall wart or battery eliminator psu.
