AIUTO!!! ALIMENTAZIONE ESTERNA ARDUINO SHIELD R3

ciao devo pilotare un motore passo passo però non come connettere l'alimentazione esterna nella basetta arduino motor shield r3 cosa devo fare per dirgli che deve utiizzare l'alimentazione esterna??? oppure come devo fare

I translated this for those who speak English:

hello I have to drive a stepper motor but not how to connect external power to the breadboard arduino motor shield r3 do I tell him he must utiizzare external power?? or as I do

federico_93:
hi, i must drive a step motor but i don't know how to connect an external power source to the arduino motor shield r3.
what must i do to tell it to use an external power source? or what must i do?

just to make things even more clear. hope this helps.

p.s. @federico_93 la punteggiatura non ha mai ucciso nessuno, quindi usala. altrimenti si fatica a capire pure in italiano.

okay anyway, I know I have two-pin jumper to tell him that must use power estrna, but I do not know Queli are pins to connect.
I can say what they are and where are they?
