This lesson describes how to control both the speed and direction of a DC motor using Python and a L293D chip.  

In Lesson 8, we used the Pi to generate pulses to control the position of a servo motor. In this lesson we use pulses to control the speed of a regular DC motor and the L293D motor control chip to reverse the direction of the current through the motor and hence the direction in which it turns.
