count passing objects

I thought you had covered it pretty well, which is why I didn't mention it.  Most conveyors run at a pretty constant speed, so it is unlikely they will need an encoder unless it is starting and stopping frequently.

There will be an encoder and the speed is consistant.

Thanks for your help guys.  I begin the prototype this next week, so I'll let you know how it turns out.
