My goal is to take a Hard drive's platter and motor assembly and make it into mouse-wheel-like Scroller for a computer.
I have found the HDDJ Project on Instructables, as well as a thread from Ladyada about using an Arduino to emulate a USB mouse.
In accordance to the Instructable, i will need 3 comparators to switch the analog output to digital that the arduino ?could read better?
What sort of code would I have to write for the Arduino to achieve this effect? Below I have a link to the firmware of the HDDJ below, but it is based off of a straight microcontroller, so I cannot tell which code drives the controller and which code is actual logic.
My circuitry/electrical skill is practically nonexistant, but I do have two years of coding in C++, so I can usually get general concepts, but i have never written code before for Arduino, so it's really all new to me.

(i apologize for the formatting, but i couldn't add links w/o one post, and i'm not about to pull some obnoxious "F1RST!!!!!" BS)
If anyone could tell a newby whether this is possible or not, i would be very thankful.
Thank all,
