Hello every one!! Actually, I just want to know what is the best component i can use to control a motor 3V or 6V with a Raspberry-Pi : Should I use an Embedded Pi or a Pi-Face ? What are the differences? I find the embedded Pi pretty difficult to use (i found that i must add an Arduino Shield to use it properly), but I don’t know if that's really true , i'm just a beginner ^^.
For more details, I want to control a motor with RFID ( So, you guess I will use a RFID shield too)
So, the Shield RFID and the motor will be connected on my Raspberry pi, but the main problem is that I don’t know if I have to use an embedded Pi or a Pi Face to connect them to the R-Pi
I prefer using Python language to program it! 
Thank you!! This is my first message!
