Hi all,

I want to use one of these devices with arduino
http://www.ultimarc.com/SpinTrak.htm

At the bottom it shows power, ground and two data.

Its this sort of encoder, two sets of pulses

Has anyone used this device before or others like it?

I keep trying the search but getting 500 internal server errors.

Thanks

Try this link. It is for a rotary encoder. Im assuming yours works in a similar fashion.

Basically you are going to use the two interupts in the arduino to monitor the rotation and determin which direction it is turning.

You're going to need to ask the maker, or experiment by hooking up the +5 and ground, and watching what comes out of the other 2 pins as you spin the knob. The "left" and "right" labels are ambiguous: they could be the same quadrature outputs as on the page that Ill Mill referenced, or they could be already decoded, and separate pulses coming out of one or the other to tell you the knob has spun to the left or right.

Its standard quadrature, see the "Incrementar Rotary Encoder" section here:
