Hello,
So I have an Arduino Uno r3 and deciding on purchasing these motor kits http://www.parallax.com/Store/Accessories/MotorServoControllers/tabid/160/List/0/SortField/4/ProductID/587/Default.aspx?txtSearch=ball+caster (http://www.parallax.com/Store/Accessories/MotorServoControllers/tabid/160/List/0/SortField/4/ProductID/587/Default.aspx?txtSearch=ball+caster)
Would they work with the SN754410 motor driver ?
and will these batteries work with the motor?

Thank you

Motor spec: Stall Current: 4.8 A
Driver:

Spec: a peak current of 1 A per channel
Motor current much greater than driver current = smoke.
You need a H-bridge driver capable of at least 4.8A
Tow of these would work for those motors:

Hi,
Would they work with the SN754410 motor driver ?
The motor has a no-load current of 0.27A and a stall current of 4.8A, but no mention of a realistic load current, so maybe it will, maybe not, but I'd go for at least a 2A driver and then add over-current protection to keep motor as well as driver safe.
and will these batteries work with the motor?
Yes.
