I’m a newbie and I dont know much about electronic, so I’m here to ask for your help.
I would like to connect 2 H-bridges to arduino to control 4 motors.
I can make it work connecting just 1 h bridge and controlling 2 motors. My problem is that as I read I need to connect the GND of my battery both to the H-Bridge and Arduino. But when I’m wiring as follows I get a short circuit (or it seems to be).
Thank you in advance for your help,
