Sorry, this was my first attempt to hook EZ B to a motor controller. I looked up several sources and thought sure everything was set up correctly but it isn't working. See the attached photos please of what I did, and maybe spot what is wrong. 12 volts in from an automotive battery, branched off to a 5 volt regulator. The strange part (to me, anyway... maybe this makes sense to someone more knowledgeable) is this; while troubleshooting, I accidently touched a ground wire to a trigger pin and the motor turned. so I tried them all and applying the ground to each pin caused each motor to spin either forward or reverse as it should if it were getting power.... Any ideas? BTW I triple checked all polarity connections are correct to the relative labels.
P.S. How to attach photos??
