Use PWM for speed control

Yes you can control speed of 12V motor with Arduino, but not directly though its I/O pins. You have to use some kind of motor driver IC like L293D or ULN2003. You can refer to this tutorial for understanding how to do it

Basically you will be using the PWM capability of Arduino to control the speed of motor by varying the duty cycle of the PWM signal
