fatal error: LiquidCrystal_I2C.h: No such file or directory

sketch_jan29a.ino:2:32: fatal error: LiquidCrystal_I2C.h: No such file or directory compilation terminated. Help!Help!

post code ...

Did you download that library? Did you install it properly? Silly question, really; it's obvious that the answer is no.

#include <Wire.h>
#include <LiquidCrystal_I2C.h>
#include <LiquidCrystal.h>
LiquidCrystal_I2C lcd(0x27,16,2);
void setup()
{
lcd.init();
lcd.backlight();
lcd.print(“www.geeetech.com”);
}
void loop()
{
}

You haven't answered Paul's question, which is likely the issue. Also, after you install the library, did you restart the IDE?

I have solved the problem.Because the communication interface between PC and Arduino UNO.There is no problem of the codes. Thanks very much.I am a green hand.

I am intrigued. Can you please explain the problem and the solution ?

#include <Wire.h>
#include <LiquidCrystal_I2C.h>
#include <LiquidCrystal.h>
LiquidCrystal_I2C lcd(0x27,16,2);
void setup()
{
lcd.init();
lcd.backlight();
lcd.print(“www.geeetech.com”);
}
void loop()

}
1.My problem is that I have no LiquidCrystal_I2C.h,so I download it from the internet,after that also have the problem fatal error: LiquidCrystal_I2C.h: No such file or directory.
2.Because sometimes the communication interface between PC and Arduino UNO is not smooth,I found that and solved.
