* Drives a unipolar, bipolar, or five phase stepper motor.
*
* When wiring multiple stepper motors to a microcontroller, you quickly run
* out of output pins, with each motor requiring 4 connections.
*
* By making use of the fact that at any time two of the four motor coils are
* the inverse of the other two, the number of control connections can be
* reduced from 4 to 2 for the unipolar and bipolar motors.
*
* A slightly modified circuit around a Darlington transistor array or an
* L293 H-bridge connects to only 2 microcontroler pins, inverts the signals
* received, and delivers the 4 (2 plus 2 inverted ones) output signals
* required for driving a stepper motor. Similarly the Arduino motor shields
* 2 direction pins may be used.
*
* The sequence of control signals for 5 phase, 5 control wires is as follows:
*
* Step C0 C1 C2 C3 C4
* 1 0 1 1 0 1
* 2 0 1 0 0 1
* 3 0 1 0 1 1
* 4 0 1 0 1 0
* 5 1 1 0 1 0
* 6 1 0 0 1 0
* 7 1 0 1 1 0
* 8 1 0 1 0 0
* 9 1 0 1 0 1
* 10 0 0 1 0 1
*
* The sequence of control signals for 4 control wires is as follows:
*
* Step C0 C1 C2 C3
* 1 1 0 1 0
* 2 0 1 1 0
* 3 0 1 0 1
* 4 1 0 0 1
*
* The sequence of controls signals for 2 control wires is as follows
* (columns C1 and C2 from above):
*
* Step C0 C1
* 1 0 1
* 2 1 1
* 3 1 0
* 4 0 0
