| // 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. | |
