we're currently doing our project and we are being bugged by our stepper motor... we had seached the net for necessary files, including datasheets and wiring diagrams, but none had helped us.... we're using a 5.1V 1A 200S/R Stepper motor with 6 wire leads......we connected it to a circuit driver, checked and rechecked every component for so many times, yet WE CANNOT MAKE IT TURN!!!!!

HELP US PLEASE.....anyone.

have you identify leads?

1a ,1b, 2a,2b

Hope following link will helpful for you.

Read the stepper motor tutorial in the Tutorials forum.
If you are still stuck, post your circuit diagram.
Give as much information as possible, about what you have done
and what happened.

to Gurpret312:
=>yes, we had identified the leads from the datasheet of the stepper motor.....
=>thanks for the link, it's not much of a help though cause we had the same info from various sites.

to DavesGarage and ExperimenterUK:
+thanks for the info..... but we're still stuck.... here is the schematic we used....with A -> A+ (white/green), B->A-(green), C->B-(red), and D->B+(white/red)....that's the last combination we used...we even tried moving three leads, keeping one lead on place, using different combinations but still, NOTHING HAPPENS....

Start by removing the motor and replacing each coil with an LED
and resistor.
Then..
Does D1 flash at a sensible steady rate ?.
Do the four test LEDs turn on and off one at a time and in order ?.

a new idea just came in....i was told that - "maybe we are not generating enough current to run the motor" - AND HE'S RIGHT!...now, may i ask anybody who happens to have a current amplifier circuit?.... i had been searching the web but i cannot find anything that we need or maybe i am looking at the wrong place???? anyone??

How do you know he is right ?.

The output of a ULN2003 doubled up, should be enough to at least move your motor
although using four power transistors instead,may be better.

Is the five volt supply to the motor able to supply an amp ?.

Just in case the ULN2003 is burnt out.. replace it.. then add LEDs as I suggested.
See what happens.

Please stop using multi coloured text in your posts, some of it is hard to read.

-we tested the current being supplied to the components....

although using four power transistors instead,may be better.
-ok, we'll give it a try...but how are we going to connect it?....can you give me a schematic diagram? (or if you got a current amplifier circuit, it'll be much better ile)
Is the five volt supply to the motor able to supply an amp ?.
-NOPE....we just found out recently....(we're newbies.....)

-ooppppsss......sorry.


one more thing, we connected LEDs to the part where there should be coil(motor), three of them flashed, two simultaneously while the other alternates, one was not blinking though the LED was in good condition, we suspects that the line/connection to the D coil, the one that didn't blink, which was connected to the 74194(specifically pin 13) was damaged....what do you think?

Does anyone have microcontroller programming software for STC15F104W (core 8051, 4 k, 128 byte, 6 I/O pin, UART ... DIL8), that works?

Hi I am looking for a assembly language program for a digital decimal counter. Time counts max limit of 2 mins starting from 2.00 mins and ending at 0.00. time is to be displayed on 4 7-segment LED displays. Edsim51 simulator to be used. Thanks
