I dont know whats wrong heres my code:


/************************************************
* name:Ultrasonic
* function: if you use a piece of paper to approach or keep it far away from the sensor.
* You will see the value displayed on the LCD changes,
* which indicates the distance between the paper and the ultrasonic sensor.

  Serial.print(uS / US_ROUNDTRIP_CM); // Convert ping time to distance in cm and   print result (0 = outside set distance range)

You should post your code [code]between code tags[/code], not inline.
It's not too late to edit your post and fix it. ;)
Have you installed the "NewPing" library?

Edit: It's available here:- NewPing library
