Hi all,

I am mechanical engineering student and want to use arduino uno in one of my projects.

Basically, i want to measure the distance very accurately. I have searched on net but no linear measurement sensor seems to work for me.

But, i am converting rotary motion from an AC motor to get linear motion with very high reduction ratio about o.o1 mm/rev. So, Even Counting rotations with rotary encoder can give me accurate distance. But, the problem is i am not very familiar with arduino and such encoders. So, my questions are...

- Does rotary encoder works with high speed (About 1140 rpm) and if not than what is it's maximum limit ?

2)Can i convert the rotation count to measure distance if i have the perfect reduction ratio ?

3)How to interface rotary encoders with arduino uno and lcd display ?

4)I want to plot a graph with deflection (the distance that i am measuring) on one of the axis with a load on other axis that i am measuring with load cell. So, how much frequency of reading i can get for plotting the graph.

Also suggest me a good rotary encoder...

Thanks
