Can i use 2 separate battery packs.
Can i connect the servo power wires and the sharp IR power wires to a breadboard and then use a voltage regulator and a battery pack to power these.And then use something like this http://www.arduino.cc/playground/Learning/9VBatteryAdapter and a separate battery pack to power the arduino.I wont have to use antoher regulator as the arduino already has one on board correct??
But do i have to connect the ground from the regulator on the breadboard to the ground on the arduino??? or the ground from the servos and sharp IR to the breadboard gnd and only the signal wires on the arduino??

and the sharp IR rangefinder to a battery??

Thanks for the prompt reply

can i not connect a separate battery pack to the regulator itself and then connect the servos directly??

Hello all,
I'm new to this forum and I'm planning on purchasing an arduino uno
for making an obstacle avoding robot.
But i have a few questions,
Since i plan on using modified servos instead of DC motors and a third unmodified servo for a sharp IR rangefinder,
will i need any shields or can i directly plug these into the microcontroller on the uno.Will i need something like the SB GVS sensor shield?

All help is appreciated
