I am very new at this and I am looking to make a system to track the revolutions of a wheel. I think that I can use an IR Reflective Sensor to track the revolutions, but then I would need a 8/8/8 interface kit to connect it to a computer and do something with the information.
The thing i am wondering is whether there is a smaller solution somewhere for an 8/8/8. I really do not need something this big with as much room for expansion. At this time, I only want to hook up a couple analog sensors and usb to the computer therefore I would not need the digital inputs or outputs and 8 analog inputs.
Since this is my first project, I am not looking to spend a lot of money. Is there anything else that would get the job done, without being that expensive? I realize that something smaller would drastically limit future expansion, but I am willing to trade expansion for cost at this point.
Surely I am not the first person with a project in which the 8/8/8 interface would probably be overkill.
