28BYJ-48 5-Volt Stepper

Hi guys!

First of all thanks for the useful things in this thread.
The arduino is really new for me, so sorry about my noob questions.
I'd like to create a motorized camera slider, first only with one 28BYJ-48.
I found Sbright33's great library(Stepper library for 28BYJ-48 · GitHub).
But I'm so confused about the wiring. Do I simply connect the 28BYJ-48 motor to the arduino board. In this case how can I get 12V? Eg from the arduino board's Vin pin?
Or do I need to use the ULN2003 board (Connect the 28BYJ-48 motor to the ULN2003 and the ULN2003 to the arduino board)?

Thanks for your answer.

Regards,
Peter
