Introduction: Raspberry PiFace L298N Bi-Directional DC Motor Control
This instructable will show you how to wire up your raspberry PiFace to allow you to control the direction of a DC Motor.
Kit Needed:
1 x DC Motor
1 x Power for the motor (I've used a 9V Battery) and connecting leads
1 x Raspberry Pi
1 x PiFace
1 x L298N Motor Driver Board (Can be purchased from eBay)
Selection of Jumper Leads/Wire depending on exactly what kit you have.

Step 1: Connecting the L289N to the PiFace
This is the bit I found the trickiest to work out however now I've got it working it seems obvious.
First connect the +5V on the L289N to the 5V on the PiFace.
Now connect the 0V on the PiFace and the negative lead from your battery/power supply to the 'power GND' on the L289N.
Connect the positive lead from your battery/power supply to the +12V on the L289N.
Connect your DC motor to one of the outputs, it doesn't matter which terminal you connect each wire to.
Put a jumper on the enable pins for the output you are using or just wire them together.
Connect the 2 input pins next to the output you are using to outputs 0 & 1 on your PiFace
You are now all connected up and ready to make your motor move!

Step 2: Make Your Motor Move!
To quickly test that this works turn output 0 on (using the emulator), this should cause the motor to spin. Turning off output 0 and turning on output 1 will make the motor spin the other way.
If you wanted you could now write some python code to control your motor, I've written this as I Cannot find a single other guide that covers L289N use with PiFace so hopefully you will find this helpful.
