Ultrasonic sensor and DC motors

Hi,

I've two questions ...

Is there a service to use ultrasonic sensor in MRL ? I've got six SR-04 for avoid obstacles on my new project .

And about DC Motors, the motor service don't work with my motor control board . There is 4 pins to drive the motors . 2 pins for each motor :

inA ON and inB OFF -> forward

InA OFF and inB ON -> backward

InA and inB OFF -> Stop

For the speed it use PWM .

In arduino service, all work well but the motor service don't work like this i guess ..
