H-Bridge For 4 Motors - Robot Car

Skip to comments Jump to end

I understand how to connect a IO tiny, ez-battery, ARC , H-bridge motor controller to two wheel robot car, easy.

Now I have a robot car that has 4 motors, do I just use 2 H-bridge controllers?

Or is their something I am missing?

thanks for help

A Two channel hbridge takes 4 digital ports. The speed of the hbridge takes 2 pwm ports. That means 6 ports in total. There’s no reason you can’t share the same ports for two hbridge unless you need them to have individual directions or speed

Hi @DJ Yeah I need 4 motors direction all controlled separate so I think I will follow your post on the other thread and go with an arduino for the # of ports and usb control.
