I'm trying to use a 16x2 LCD screen with the with the YWrobot shield on the Arduino UNO but the compiler does not seem to recognise the command LiquidCrystal_I2C.h. How can I solve this problem?

I don’t think this is one of the built-in libraries, so did you install the library where the Arduino IDE expects to find it? (http://arduino.cc/en/Guide/Libraries)

If you did, then did you restart the Arduino IDE after you installed the library?
