    Please put electronic scheme. Where motors coils to be highlighted.Thank you!

    Drawings do not come out right.How to define the origin?Pressing keys 1, 2, 3 or pg up, pg down, nothing happens, although the board Arduino LED indicates that receives data.

    And I have the same problem.drawings do not come out right.how to define the origin?Pressing keys 1, 2, 3 or pg up, pg down, nothing happens, although the board Arduino LED indicates that receives data.Here are you Hisoka files.
