Hello!

I want to know how to make a stepper motor change its direction. what is the sequence for clockwise and anticloakwise rotation? I am using ULN2003A for interfacing the stepper to microcontroller.
 

I am supposed you are using unipolar stepper motor which has 6 pins, so 2 of them is common. If you want to rotate it for one direction find the not common pins, there are 4 you have to give pulse sequence like this

1000
0100
0010
0001

if you want to change direction, get previous sequence bottom to top,

0001
0010
0100
1000

if you are using stepper motor of different type, same principle is there. Hope this diagram will help to find out pins of motor.

I am trying to rotate my stepper motor clockwise using above sequence but It is not working.
Please guide me.
 

Post your code and circuit.

Make sure wires of the stepper motor are correctly connected..
