    I need to connect THIS
    http://www.pololu.com/catalog/product/1183/pictures

    to THIS
    http://www.pjrc.com/store/teensy_pins.html

    I Need to connect these two things and I have very little knowledge about electronics... Can someone help me out?

    I need to know the entire process... Which wires to use? Is there a specific kind? What wires to connect to what parts? Please be as detailed as possible in your answer as I am incredibly green about this stuff.

    Thanks in advance- I greatly appreciate it!


    Mike.

    Te page for the stepper driver shows the
    on the bottom right.
    Which pins of the Teensy you use depends on your application (which, of course, you'll have to write yourself).
    Use any thin wire you have lying around for the connection from Teensy to the driver. Use thick wire (AWG 20 or thickrt) for the wires from the driver to the motor and from the power supply to the driver.

    Thank you. That helps.

    You see... I am such a newb that I do not even know that the way you connect the two devices must be specific to the device you are attaching it to...Ouch- do I feel dumb!

    So in this case it's for a Stepper Motor... I have the firmware and software for it already. So I'm good on that.

    So... I need to connect it (once both chips are wired together properly) to the Stepper Motor. So I guess there must be a specific way to wire it that is configured for a Stepper Motor? I'm not sure if matters but the stepper motor will be to run a z axis positioner. Am I understanding this correctly or way off again? lol.

    Do you think there might be a better place to be posting this? Perhaps a stepper motor forum?

    Thank you very much for your answer- it means a lot to me.

    The wiring is shown on the diagram on the stepper motor article page. Have you read the FAQ on that page? Wehre exactly is the problem?

    The problem is that I'm an idiot and have never done something like this before.
