Motor shield BTN8982 nad hall sensor


i´m brand new and have no idea from programming.
I know a little bit of Elektronics.

Ok, I want to build a small e-bobby car for my son. I used the arduino board and put on a infineon Motorshield BTN8982. I also found a Sensor at work for gaspadels used in cars. (Hall Effect Sensor AB 9168000010)

Now a want to program the motorspeed with the effect hall sensor.

Please give me an advice or an example on which I can work...

THANKS. 710er
