+ 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.
