	The Arduino LCD module is used to display characters or numbers, with 16x2 or 20x4 sized LCD displays being commonly used. This document covers LCDs that support I2C communication. Using the I2C interface instead of a typical parallel interface reduces the number of pins required and simplifies wiring. It can be easily connected to an Arduino board to visually represent information in various projects.
