    Actually, LCD I2C is composed of a normal LCD, an I2C module and a potentiometer. LCD I2C uses I2C interface, so it has 4 pins: GND pin: needs to be connected to GND (0V). VCC pin: the power supply for the LCD, needs to be connected to VCC (5V). LCD I2C 16x2 includes 16 columns and 2 rows. the conlums and rows are indexed from 0.
    A typical I2C LCD display consists of an HD44780 based character LCD display and an I2C LCD adapter. Let us get to know them one by one. True to their name, these LCDs are ideal for displaying only text/characters. A 16×2 character LCD, for example, has an LED backlight and can display 32 ASCII characters in two rows of 16 characters each.
    The advantage of an I2C LCD is that the wiring is very simple. You only need two data pins to control the LCD. Standard LCDs typically require around 12 connections, which can be a problem if you do not have many GPIO pins available.
    The PCF8574 chip is used in the I2C module on the back of the LCD. The wiring diagram below shows you how to connect the I2C LCD to the Arduino. Wiring an I2C LCD is a lot easier than connecting a standard LCD. You only need to connect 4 pins instead of 12. The connections are also given in the table below.
