    I want to learn how to control some small circuits through my parallel
    port but I do not want to damage my port. What can I use to make sure
    that I don't draw too much power or any other problems that may occur.

    I thank you.

    Opto-isolators would be a good option.

    Thank you but I'm new to electronics, ok fairly new I tinkered when I
    was a kid but forgot most of this stuff. Anyway What is a Opto-isolator?
    And how do i use one?
    A link ore simple diagram explaining this would be appreciated, a goggle
    search made my mind explode all I could get looked like engineering

    Again I thank you

    Not cheap but good: Check out (they can deliver all over the
    world I believe, I think ther're in the US as well) and search for K8000.

    Greetings and good luck with Your project!
