Hello,
The L298n video shows DJ attaching the bridge and ez-b to a single power supply and it looks like the ground for both circuits goes through the ez-b.
I need to use a 12V supply to the ez-b and a 7.2V supply to the bridge.
How does this wiring setup differ?
Thanks...

I need to know how to wire it with dual power supplies, one for the ez-b and the other for my motors
Is it possible to use two separate power sources with an h-bridge?
Specifically, I want my motors to be driven by a 7.2V power source while my ez-b is controlled by a 12V power source.
If I wire them using below diagram, I would be feeding 12V into the h-bridge. The problem is, I'm not sure the little motors in my OWI-535 robot arm can handle 12V but I'm pretty sure 7.2V will be okay.

Does my question even make sense?
So where is the ground connection for the EZ-B?
I was afraid current might flow the wrong direction if I did that because there would be potential between the EZ-B ground and the 7.2V battery ground.
I guess I need to break out my multi-tester
Again, the answer is connect the GND of the two batteries together. That is the answer to your question
Also, the EZ-B does not require 12v. You can simply connect the EZ-B to the same power source as the motor and not need two power sources
