In this exercise, we use DC Motor control using PWM for speed control. The electronic driver is called an H-Bridge that will allow the motor to turn either way if hooked up properly. That will be shown in a follow-on Blog entry.
We us a 31162MP H-Driver as hooked up to the Raspberry Pi 2B as shown:

The specification for the 31162MP H-Driver board is:

Test code using a single speed is shown below. The speed can be set depending on the PWM pulse width of 0-1023. Below a value of about 150, the motor may not turn.
