I'm relativly new to all these sorts of thing; however, I've been given a task to design a relativly cheap (under $100) for a circuit/bread board that connects a stepper motor, and 2 optical encoders to the computer.
The encoder I'm using is this:

The bipolar stepper motor I'm using is this:

I am planning to connect and control these devices via the parallel port.
I have semi-figured out how to connect the stepper motor to the parallel port using the dual H-bridge IC SN754410, where the 4 output are connected to 4 of the data pin on the parallel port (with optical isolators of course). One thing I have yet to figure out is where am I suppose to put resistor and capacitors on the board?
For the encoders, I've been told various things. Some people say that you need an A/D converter for connecting it to the parallel port, while some say I don't. So, which one is it?
Furthermore, I am using pin 1 on the parallel port to power the IC, and the 2 encoders, and I was wondering, is that enough?
