Installation of the library

Before you can transfer the code example to your Arduino, you must
install first the additional library LiquidCrystal_I2C.

This library allows you an easy and fast usage of the display.

Therefore, open the library manager on your Arduino soware.

Search now in the library manager for the LiquidCrystal_I2C library and
install it.
