Motor shield Link
I intend to use that to drive two 12v dc motors that will give mobility to my prototype..
Can you help me ?

This is the shield i'm talking about...

DirA and DirB (12 & 13) look to be direction of the motor. Usually these work that high is one way and low the other. A simple Digital on/off (or Set(port,on/off)) should do that.
PWMA and PWMB (3 & 11) for speed control of each motor, PWM on each of the ports to set the speed.
BrakeA and BrakeB (8 & 9) to apply a brake to the motors (not really required), apply a high to these to instantly stop the motor.
That is assumption, check it out first. But it does look very much like the Dagu 4 motor controller. Check my cloud uploads for an example project for controlling these. There is a Dagu topic too which has more info in than I've put above...
Edit: added links.
Edit 2: Let me know how you get on with the above, I'm always interested in knowing if what I've advised has worked or not but often people don't give the feedback (for whatever reason).
How is it even possible that digital ports can't respond any longer, actually ?
Thanks a lot.
Also, while I'm replying, I looked in to the board a bit more and found this;
Which basically translates to what I said above in my other post, plus a bit of info on the current sensors (connect A0 and A1 to 2 ADC ports and read them for the current if you want to, 3.3v = 2A, I'm too tired to work out the multiplier needed (it's 2:40am here).
