Making an Arduino-based robot with motor controller shield - what's the best battery(s) to use?
I tried at first using a 9V battery to supply it, but the current was way too low. I figure I can either use 6 AA batteries in series, or get a ~9.6V rechargeable RC car type battery. The Arduino is powered by a separate 9V battery.
It's a simple setup so I'll just describe it here;
-[battery] goes into the 8-30V input on the motor controller.
-two sets of +/- wires go from the motor controller's 'Motor A' slot to the left motor and 'Motor B' to the right motor, separately
-the motors are hooked up to 58:1 gearboxes and turn 5cm rubber wheels, for differential drive.
Seems like I might have chosen the wrong motor controller shield for the motors, but if I can make it work somehow, then I will.
