Arduino circuit and sketch

Things need to take note:
1. You need to download and install the "New LiquidCrystal" library (https://bitbucket.org/)
2. If you encounter the "<Wire.h> no such file or directory" error, you need to copy the Wire library under the same "library" folder as the LiquidCrystal_I2C library.
