Wiring a motor to the RPi?

What do I need?

I am told that I need some transitors. I have a 12v powerpack and 2 x12v motors. How do I set this up so that I don't blow-up the RPi and that I can control the motors through the GPIO?

I have a gertboard on the way but I would like to see if I can do it without it first.

I have little knowlegde about transitors and electronics but I do know how to build circuits.

One option is to use the gertboard and drop in an atmega 328.

With this setup the PI will be the brain part and the arduino the muscle portion of the setup.
the Gertboard has already 2 motor interface on it.
And the arduino has 6 PWM build in.

It will then be easy for the PI to just send the PWM values to the arduino via the serial port or I2C as you wish.

The problem is: How do I do that?
