I have 4 motors that I want to control with a H-bridge. Looking at the hook up to the EZ-B control board it takes 5 pins to control 1 motor or 2 if you want them to run the same. So to control 4 motors it will take 20 pins? That will leave no room to control anything else.

Actually the motor driver takes 4 signal pins to drive two bi-directional dc motors. The other pin is 5V which I believe you could actually use from the 4 lines already being used. so if you want to drive 4 motors you have to use 8 ports on the EZ-B. The two motors will run differently as they are controlled by two different pwm signals.
@How,
Why don't you use ESC's. There are already a few posts overhere that go into that matter. The advantage is you only need one port on the EZ-B for each motor.
This ESC you'll find in many RC-stores and webshops:
Graupner ESC 6-12V/15Amp
Not too expensive and very accurate.
Good luck
Thanks for the advice guys. I am new at this stuff and can use all the help. So the H-bridge runs 2 motors each 1 by it's self. I will look for the Graupner ESC 6-12v/15Amp.
Thank You,
@HOW,
Idd, one H-bridge = 2 motors This video is the best tutorial you can get :

One ESC = 1 motor = 1 port on the EZ-B
You're welcome
