I'm trying to start with the SainSmart 4x20 serial LCD, and copied the library to the Arduino library:
LiquidCrystal_I2C.h is included. But when I try to compile an example sketch it says
Arduino: 1.7.0 (Windows 7), Board: "Arduino Uno"
HelloWorld_i2c.pde:2:31: fatal error: LiquidCrystal_I2C.h: No such file or directory
Any ideas how to fix this?
