Ultrasonic Radar

Hi. Using Ultrasonic Radar with HBridgePWM it seems that unless you have a 1-180 degree sweep of the HC-SR04 it only asks the bridge to turn one way. I have tried different sweep angles with no success. I would like a sweep of 45-135 degree. Anybody know the answer to my problem?

Hey westies,would having the sensor moving left to right on a servo help?

Or maybe just en extra set of sensors to cover a wider angle, etc? I don't know the answer but someone here will. : )


Thanks for your input,it appears that these sensors can be a little un reliable so trying different ones gave me better results They are cheap on EBay.
