Motor Driver question

hallo

i'm trying to build 'start here' robot using arduino as the brain 2 gear motor as the driving force.one of the forumer has point out to me that i need a motor driver to control the motor for forward and reverse movement,

my question is(sorry if sound stupid) do i need 2 motor driver for the 2 gear motor or 1 motor driver is enough.and how to use this motor driver.

thanks for the help.truly preciated

 

adafruit motor shield

I highly recommend this:

http://www.ladyada.net/make/mshield/

it is easy to build, easy to use, and lets you control up to 4 gear motors, or 2 stepper motors.

1 driver
depends on the driver, but most drivers are a dual H-bridge, which works for two motors.
