Double ultrasonic parking sensor

Hi,

I am developing a project that has the same concept as a parking sensor. As an object is in range of a HC-SR04 a buzz is sent to a vibrating motor. As the object gets closer, the vibration will pulse faster.

I have the code working well for one ultrasonic sensor, however I want to add a second ultrasonic that will work off the same output. Is this possible without having a messy output vibration or will I have to add another output?

Thanks in advance

Get the distance from both sensors, find the smaller distance and adjust the vibration accordingly.

Do you mean you want to trigger both SR04 at the same time? Are the SR04 scanning the same area?

How will you discern between the received signals? Can you post a diagram of how you will layout the SR04 units?

Thanks.. Tom... :)
