Can you find me the site which has special potentiometer? perhaps I will check first.
and thanks for your advise.
Some quick google searches should bring up information here. Alternatively, read datasheets and look up parts on digikey.
Hi all, can u also suggest me common rotary encoder? low cost rotary encoder should be better, because my hardware didn't need very fast rotation.
Rotary encoders are much more expensive than potentiometers: where a decent pot might cost ~$0.50, a non-mechanical rotary encoder will cost ~$20.00. Rotary encoders are also better for faster movement as compared to slower, since they have lower resolution, where a potentiometer is more cost-effective.
P.S.: Please don't double-post, just edit.
