Using Ezb 3 With An H-Bridge

Well, I sold a lot of stuff and I think I will almost get my Pepper robot. But, I did not move the EZB 3 nor the RAD base. So, I had some 4 wire H-bridges laying around and figured I would try to get a little bit of fun going.

Well, I wired everything up and when I hit the control panel, when I say forward it would turn to the right and backwards to the left. I corrected this by swapping some wires. Now, It goes forward and reverse just fine. But, when I try to go right and left , it just BUMPS.

I have gotten an answer on this long ago, but I forget where. I believe it was Rich that gave me the answer, or maybe Rich.R.

Anyways, any help is appreciated.

Easy fix. Swap more wires around or change the ports in the controls. If left and right are just bumping you have both ports set high. One of your left motor controls is in right motor and vice versa.

Post the port numbers and Ill correct them for you although it's likely that left motor b and right motor b are reversed.
OK, I will try this.

Thanks, Rich. You are the man.

It will take me a little while to check all of this. I am doing it in steps and I have completely run out of breath. So , maybe a day or two. I will let you know.
