    The esiest way to do this is using an H_Bridge IC like the L293D that is controlled with a simple interface.
    Look at this link;
    H_Bridge motor driver IC

    A better microcontroller to use is a PIC with a PWM output to control speed by writing a simple value to a register (I don't know whether the arduino has a PWM output otherwise you will have to control the pulsing. The listed IC also support bi-directional motors.
