    hi, could you tell me with this file :
    Arduino code: 2DOF and 2 pins direction Hbridge 1.2 with presets
    RacingMat , November 8, 2013 , for Firmware Interfaces
    source code
    what kind of connection made between Arduino and MM for two engines ?
    Thanks.

    Hello
    Glad you find the answer
    :)
    Please put a link instead of copy/paste
    It's easier to update or correct if the information is not spread in many places...
    Yours

    excuse my insistence , I can not understand the list of pins with the photo.
    in the picture there are pins on MM that on the list there are not , why ?
    and ' can do a bit of clarity , I not would burn some component ,
    await response to start connections between Arduino and MM ,
    Thank You

    hi , thanks for reply , I still have Doubts about A1 and A0 , but do not go on Arduino ?
    Please could you take the attached picture and complete the connections of the potentiometers simply with the p a i n t .
    I'd appreciate it , thanks again and sorry insistence .

    I don't really understand your sentence
    Pot1 on A0 (Analog 0)
    Pot2 on A1

    I wrote A4 and A5 in the code? I should correct the pinout
    but it's nice to have a look a the code anyway, and to understand what is done
