I just got a 28BYJ48 stepper motor from ebay. I don't have a ULN2003 yet so I thought I would just test it with four pushbuttons or NPN transistors. The thing is, every URL2003 driver schematic I find have no resistors. It it okay to drive the motor directly off 5v? And when I DO get the ULN2003, do the bases not need to be limited like transistors' normally are?
Thanks
