I have been trying to build a BLDC motor using an H-Bridge Circuit, based on the instructions from https://www.instructables.com/id/BLDC-Motor-Using-PVC/ and the attached schematic. I think I'm close, but my circuit is not working correctly -- the power isn't running through the circuit from the batteries. I've tried isolating each of the four quadrants to see whether they work, but have frustratingly found some individual quadrants work sometimes but cannot figure out the problem. I've attached the setup on my breadboard to this post as a pdf printed from a layout I drew on fritzing. I suspect that it has something to do with the way the ground wires are setup, but I haven't been able to figure out the problem. I would very much appreciate any help or insight that anyone may have.
