- Stepper Motor Control - speed control
- 
- This program drives a unipolar or bipolar stepper motor. 
- The motor is attached to digital pins 8 - 11 of the Arduino.
- A potentiometer is connected to analog input 0.
- 
- The motor will rotate in a clockwise direction. The higher the potentiometer value,
- the faster the motor speed. Because setSpeed() sets the delay between steps, 
- you may notice the motor is less responsive to changes in the sensor value at
- low speeds.
