I2C Control Boards allow you to connect an LCD Display to your Arduino using only 4 wires.
Note: I2C is an Addressable Communication Protocol. 0x27 should be the default address of the display. If this does not work you will have to find the address by running a sketch designed to find I2C address on an Arduino: https://playground.arduino.cc/Main/I2cScanner/
