Hello,
I am pretty new in electronic so I may not used correct terms but here is my problem:
my project consists of an RC car using arduino and L293D motor driver with brushed 12v DC motor.
I have a 9v battery with voltage regulator (5v and 3.3v like this) for the arduino and the L293D internal voltage.
I would like to use 2*9volts battery for the motor power.
here is really simplifed schema and my question regards the question mark on right
If I put the 2 batteries in parallel to get more voltage for the motor, can I plug the ground of the batteries to the voltage regulator used for the arduino?
Can it damage anything?
Thanks
