Welcome to SoR.

By driver I assume you are referring to motor driver. A motor driver circuit is one that can take the very small amount of power that a microcontroller is able to provide and control a motor or relay. Depending on which motor driver you acquire you should be able to control any type of motor. The basic ones are permanent magnet DC motors, Stepper motors, and brush-less. You can control the speed of a motor by turning the motor on and off really fast using "pulse width modulation" you will see it referred to as PWM on this forum.

Check google for H-Bridge circuits. There are hundreds listed there.
