I HAVE CHECKED IT WITH THE MULTIMETER AND IT IS PERFECTLY ALL RIGHT !

@Mr. Alex, Yeah sir .. it doesnt run !

Mr. Alex, I am using the power supply of 12v, 800mA . And the wiring is not coloured. Its just the way as u see in the link I have provided above. I have checked everything. Am working on it since a week Sir . I am just stuck at this place and couldnt proceed further.
I guess all the 4 motors arent working ..! I have just tried it and the outcome is NIL ..!! :(
but am able to see the LED glow when i connect it to the wires and on rotating the shaft..! Its the only factor that is still making me hopeful about its working !

Sir, this is exactly the type of stepper motor I have used ..
Firstly, I want to ask you a question ..
are the driver IC's able to drive UNIPOLAR motors too .. I have read that L293D is used for unipolar and bipolar too...!!
yes Mr.Alex. I tried it just now . It wasnt rotating .. But I read in a website that if the resistance of combination of two live wires is double that of live-ground combination, then
that motor is working. How far can this statement be true.. ?
I have bought 4 stepper motors & I dont think...
Hi Mr.Alex,
I might be wrong in specifying the exact current rating ..but the rest of the details abt the resitance and the voltage rating are correct.. As the one's i bought were from a very local company from my place, I didnt even found out any data sheet .
So far i have tried out all the...
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...
