// This Arduino example demonstrates bidirectional operation of a 
// 28BYJ-48, which is readily available on eBay for $4.25 inc shipping,
// using a ULN2003 interface board to drive the stepper. The 28BYJ-48 
// motor is a 4-phase, 8-beat motor, geared down by a factor of 64. One 
// bipolar winding is on motor pins 1,3 and the other on motor pins 2,4. 
// Refer to the manufacturer's documentation of Changzhou Fulling 
// Motor Co., Ltd., among others.  The step angle is 5.625/64 and the 
// operating Frequency is 100pps. Current draw is 92mA.
