Hey guys,
as the project rolls on we are sort of making it all work.. somehow.
we are running 12v from batteries into the arduino motor shield. then controlling the 2 dc motors is all good- one in channel a and one in channel b.
but i know that the motor shield only gives max 2A per channel. the motor in channel b is a 12v dc motor and we need more torque out of it but still want to run it through arduino.
the question now arises:
is it possible to hook up another battery in between the arduino motor shield and the dc motor ?
aka- have 12v into the arduino to power it. then have seperate battery in between the motor shield and the dc motor ?
i read that it is possible to hook up an external power source for a servo- do you just hook up the battery to the power cable and ground to ground ??
thank you
