I want to make this into a library for everyone to use.
Can you find any mistakes or portions of code that are confusing?
If so I will try to clarify.
Please test this if you have a stepper motor!
// 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. // Vin w USB power is 4.5v too slow for testing use 5v pin. See attached PDE file
