Programming DC Dual Axis Gear Motor's

I have been working with an Arduino UNO. However, I can seem to find a program that will run all four DC dual axis gear motor's. I was wondering if anyone had and suggestions or examples that I could try? Also i have been told that I need a separate power source for the motor board. Is this true? If so what should I use to power the board?

Hi, Need more information.

  • What motors? Voltage,current
  • what motor drivers?

This is the link with the robot kit on it. I'm not sure what your asking so I think this will help.
