In one of my project i have to rotate potentiometer knob through microcontroller . I have to distribute the 360 degree rotation of knob in ten steps. Is their any other way without using servo or stepper motor ??

Maybe,
But what's wrong with using a servo or stepper ?

Also,
If all you need is variable resistance, you'll do much better with a digital potentiometer instead of rotating a mechanical one...
 

for me its better to user stepper motor since you are controlling it by steps
 

I tried with stepper but running a stepper motor is a heck of job. Firstly finding a right sequence to rotate is difficult , then it draws too much current ( about 1 to 1.5 amperes) , thirdly stpper motor i tried with rotates with too much slow speed.


I haven't tried servo, will it be easy doing it? Cant there be some other electro mechanical mechanism to do the job?

A hobby grade servo is easy to rotate to a desired angle - this is done with a PWM peripherial.
But again, why don't you use a digital potentiometer ?
 

digital potentiometer ic's are difficult to find here in Pakistan or you will have to import it, which takes time , which i dont have :). Can you name some commonly used digital potentiometers so i should have a look at local market?
