A potentiometer would probably be easiest if you can find one that's durable enough and allows continuous rotation.

A couple links for fairly inexpensive encoders:

There are also ICs (e.g. AS5030) that will sense the rotational position of a magnet placed over them. Offhand I can't seem to find any retail breakouts for them. The least expensive option but also the most difficult to implement.


Do I need an encoder as I am using potentiometer ?

No, you just need an encoder or a pot. Personally I've never seen a potentiometer used for continuous rotation and would expect them to be expensive; encoders seem better suited to this type of purpose.

I don't see why you would need a "continuous rotation" pot for an inverted pendulum.

You might also look into hall effect sensors if you want your inverted pendulum to run for long periods of time, and don't want to worry about a potentiometer wearing out.
