But i'm new on this area and have no idea how i can realize that.
What for a external power i need?
What things i have to observe by the exteral power?


Thank you in advance

It would be better to use a specialized stepper motor driver such as the Pololu A4988 as that will allow the use of a much higher motor supply voltage for better performance. it will also make the programming much simpler.
