Hi everyone ..
I have a stepper motor that of a local manufacturer.. unipolar,5-wire,with a requirement of 12v and 400 mA .. I have used two driver IC's L293D and ULN2004A to make it run and am unable to do it ..
I dont know if it is working or not ? I tried the connections as in the following link
Stepper Motor interfacing with Microcontrollers tutorial: Connecting Stepper Motor : 8051 Microcontroller Projects AVR PIC Projects Tutorials Ebooks Libraries codes
but everything in vain ..!
I have found the usage of LED to make it glow while rotating the shaft and drawing the conclusion that the stepper motor works ?? Is it the correct way ?
and like DC motors ; can we test the stepper motor directly by connecting the DC adapter to it ..? I even tried this but couldnt make it run !
So please say me ways to make it run ! Are driver IC's necessary to make it run ? Can't we run the stepper motor by providing necessary voltage and current rating ? What other factors should I consider and what all information should I know about the stepper motor ?
Awaiting your reply ..

The resistance of live-live wires 145.12 ohms and that of live and ground wire is 72.55 ohms ..
