I'm trying to get a Rover 5 chassis going with EZ and an H-298 H-Bridge. I've watched DJ's video but I have a couple of questions. I'm using an external source to power the motors, connected to vcc and gnd. I have all the signal wires connected to digital pins on the EZ.
1. Do I need to connect the +5V line, or will the board draw power from the external (motor) power?
2. Do I need to clip the 2 inner enable pins and bridge the remaining 2 pins and connect them to a PWM port? Or should I connect each of the outer pins to separate digital pins, and then add separate PWM panels for each motor?
TIA.
I am finding I needed to use both to regulate the speed of one side of a robot otherwise it tended to veer off to the right all the time. By using separate PWM for each motor I can correct for other mechanical or motor inequalities.
