AVR-Chat

G'day all

For a few days Yahoo has bumped off the list it seems...

I posted the following on AVRfreaks so some of you may see this twice.
I need to know exactly where a stepper motor is positioned at any time.
By Googling I found some potentiometric position sensors, which I guess
will do by feeding it into an A/D and reading back the voltage.

If there is a digital type of sensor that would give me discreet positions
from 0-255 that would be perfect, and as some of you are geniuses on
the subject, you may be able to point me in the right direction without having
to wade some 1600 pages in Google.Basically the program would check where
the motor is located, find out where it needs to be and issue the correct
number of pulses to take it there( backward or forward), then check that
is in fact there. This will be controlling a valve that needs to open a
certain amount.

Regards
