    I want to control a Bi-Polar stepper motor using an H-Bridge and an Arduino UNO Rev3 as the controller. I have two questions:

    1. I would like to know if there is any advantage to using 4-wire control over 2-wire control with the Arduino Uno Rev3?

    Here is the tutorial I'm following:
    https://itp.nyu.edu/physcomp/lessons/dc-motors/stepper-motors/

    They mention using an L293D H-Bridge, but I will be using an SN754410 H-Bridge since I read that it is a pin-to-pin replacement for the L293D and I need to drive about 700mA of current.

    I'm assuming it will work as a pin-to-pin replacement with the 4-wire control setup.
    2. Is the SN754410 also a pin-to-pin replacement with the 2-wire control setup?

    Pro = less wires/pins used..
    Con = more components to fail..

    Thanks for responding. Are there any performance differences?
