I GOT A PING))) SENSOR YESTERDAY
NOW I KNOW HOW DOES IT WORK
BUT I NOW, I NEED TO KNOW WHAT SHOULD I DO, TO TURN ON AN LED OR MOTOR WHEN THE SENSOR REACHES IN THE MIDDLE OF TWO NUMBERS.

WHAT SHOULD I CHANGE IN THE CODE

IF YOU DONT REALLY UNDERSTAND WHAT I MEAN, POST A COMMENT

/* Ping))) Sensor
 
   This sketch reads a PING))) ultrasonic rangefinder and returns the
   distance to the closest object in range. To do this, it sends a pulse
   to the sensor to initiate a reading, then listens for a pulse
   to return.  The length of the returning pulse is proportional to
   the distance of the object from the sensor.
     
   The circuit:
    * +V connection of the PING))) attached to +5V
    * GND connection of the PING))) attached to ground
    * SIG connection of the PING))) attached to digital pin 7

because im a 13 years old beginner.
and i really need help so that i will be able to make a robot.

and can a little part of code can be moved anywhere else and will it still work?  smiley-eek-blue

Furlongs? What you have written doesn't make sense. Could you tell us what you think the problem is?

i think the problem is that my arduino uno cant read the cm and inches.i just need help for something that can replace the cm and inches

what i have written is:

Please back to your last post,click on "modify", then highlight the code, then click on the # icon on the editor's toolbar.
Then click on "save".

No, not the "quote" icon, the Code (#) icon.
You can go back and modify old posts.
