hm. I would actually like to directly attach a potentiometer to my computer. I am sure there are some hacks which will have the same effect, but I want to figure out how to do it my (maybe more complicated) way:
take some analog sensor (i.e. potentiometer) --> connect it to some type of A/D converter --> connect it via USB to a computer --> have the computer recognize the device as the scroll wheel of a mouse
In the end I want a little USB dongle, with a twistable nob, which I can just plug into my laptop and scroll through text.
(and yes, its a gross oversimplification of what will be going on.)
Is this clearer?
Any suggestions?
