hello,
I have a steppr moter as shown in photos blow








it's has a complete bord with ic l9935
this from my car from bmw flip screen it's open and close the monitor but i replaced the screen with custom montior and i want to control the stepper moter form arduino for car pc project

this is a link for datasheet for l9935

http://www.st.com/web/en/resource/technical/document/datasheet/CD00001211.pdf

i connect the power + - 12 to the ship
i don't know how to connect it to arduino



help please

thanks

First I think you'll need to carefully trace which wires from the ribbon connector
go to which pins on the IC (and the two power supplies too).  The chip uses 5V SPI
so you'll want to connect up SCK, MISO, MOSI and SS to SCK, SDO, SDI and CSN on
the L9935.

The datasheet isn't great I'm afraid - the drive sequence tables don't explain
the actual meaning of the bits in SPI bytes, but you should be able to just use
the sequence documented.

thank you for reply
i think this will so hard can you tell me what is the best stepper driver
