Before wiring the LCD screen to your Arduino or Genuino board we suggest to solder a pin header strip to the 14 (or 16) pin count connector of the LCD screen, as you can see in the image above. To wire your LCD screen to your board, connect the following pins: LCD RS pin to digital pin 12.
How do I program an Arduino LCD display?
The Setup
Insert your LCD screen into your breadboard vertically such that each pin has its own separate line on the board.
Insert your potentiometer in the same way.
Connect 5v and GND from Arduino to the + / - rails on your breadboard. ...
Connect Pins 1 and 16 from the LCD screen to the negative power rail.

You can easily interface a liquid crystal display (LCD) with an Arduino to provide a user interface. ... Liquid crystal displays (LCDs) are a commonly used to display data in devices such as calculators, microwave ovens, and many other electronic devices..
A 'potentiometer' is typically used to implement a variable voltage divider which otherwise would require two resistors. In this case the potentiometer is used to provide a voltage at pin 3 that is used to adjust the contrast of the LCD. Many LCDs function very well when this voltage is around 0.4v.
They work by using liquid crystals to produce an image. The liquid crystals are embedded into the display screen, and there's some form of backlight used to illuminate them. ... When the backlight is activated, it produces light that is somewhat obstructed by the liquid crystals.
The VEE pin is used to adjust the display contrast. We can use a potentiometer to connect VEE to a suitable positive voltage below +5 V. The Led+ and Led- pins are used to turn on the display backlight (connect them to +5 V and ground, respectively).
Note: Most Segment, Character and Graphic displays will operate with a VDD of 5V or 3.3V. It may be possible to drive the display with as little as 3.0V, but the module may not perform very well in colder temperatures. The colder the ambient temperature, the more power is required to drive the segments.
Connect the voltmeter's terminals to the input and output terminals on the pot. Turn the voltmeter on and turn the dial to feed a signal. Turn the knob on top of your pot to adjust the signal. If the signal reading on the voltmeter goes up and down when you turn the knob, your potentiometer works.
