accelstepper help needed

[rpt007]

Try this:

28BYJ-48 Stepper Motor with ULN2003 driver and Arduino Uno – 42 Bots

which comes with some explanation about this motor and how to be driven by AccelStepper library.

If I am not mistaken, somebody has modified AccelStepper into a version which even should be more suitable for this special little motor.
