I liked connect stepper motor to arduino with resistors and transistors, but I dont know how make this. My stepper motor have 5 wires. Thanks for your help... ;)
Hi, I little more info please, what motor, what voltage, etc......... Go and buy a stepper motor drive module, much simpler, unless the stepper is very powerful and needs a few Amps to go!
If its a low current high-impedance unipolar stepper, then normal way is to drive with an ULN2803 which can handle upto 0.5A max and has freewheel diodes built in (absolute requirement). Google will find circuits/examples no doubt.
5-wire steppers are almost certainly unipolar...
