If you are using the arduino-1.0.1 environment, then you must replace "WProgram.h" with "Arduino.h" - works like a charm!

I think, you should set a timout for "pulseIn" in "timing" method. Because if there are multiple sensors, one sensor blocks others, because one sensor waits for an echo for a long time.

Thanks for your effort. This library has been very helpful in my project.

I'm a newbie, so bear with me.

When I try to verify the sketch, it gives me the following error code:

In file included from UltrasonicDemo.cpp:1:
/Users/sabrinawhite/Documents/Arduino/libraries/Ultrasonic/Ultrasonic.h:11:22: error: WProgram.h: No such file or directory

How do I fix this?
