I wired two h-bridges (from the EZ-Robot store) to the 4 motors on my Dagu 4WD Thumper. I wired one h-bridge to the right side wheels (each wheel gets one of the dual outputs from the bridge). And the other h-bridge to the left side wheels.
My question is: can one digital output from the EZ-B board be used to drive two digital inputs on the h-bridge? Specifically I want to jumper IN1 to IN3 and IN2 to IN4 and drive each pair with an output from the EZ-B board. This way the right-side wheels will move in sync but will have separate power sources. Same for the left-side wheels.
