    heya guys

    i need som help cuz ime lost on this
    i got this fun hard drive motor 3 fase whit ground point and ordered an 4-bit Bidirectional Universal Shift Register,
    now what i ordered wasnt exactly what i got so instead of waiting 1 month for parts i whould like to use these somehow,

    now ive been playing whit this for a bit whit my arduino as a PWN module (my last pot got burned so i coudnt use an 555) but i was unable to do any shifting whit only 1 led as to show any progress,

    tryed high low combinations on difrent inputs but it dos nothing,
    i got my IC info from this link http://html.alldatasheet.com/html-pdf/246780/RENESAS/HD74LS194AP/298/1/HD74LS194AP.html

    if someone knows this chip or knows how to work whit it i whould be thankfull :)
