Can you show us a picture? What is this motor in, does it have its own housing, holding it in place. You might not be able to change it.Post a picture, that way we will have a better understanding of what your trying to do.
i want to amplify the volts produced by the line follower to power its dc motor, since its to weak to carry my sla 7v battery so i will modify my dc motor to a bigger and stronger one,. the logic of hbridge is correct but the hbridge wont work at all.
the power source of the robot is also from the sla battery.
