Darlington and H-bridges

Got some chips from

The first is a UNL 2803 Darlington Transistor Array which I hope to use to control a stepper motor with, I have 8 of those, they are cheap and if they work I can use them on the boe-bot or other projects.

Also got 3 SN754410ne chips, they are H-Bridge Motor Drivers.

Don't know if it will work but also got 3 C-PS2501-4 optoisolators with the idea that maybee they can be put between the motor drivers and the microprocessor. I really don't know what I am doing and the components are cheap enought for what I am doing. If they work it is fine, if not no big deal.

This is a picture of the ICs from a beat fuji finepix cam I just got.
