Introduction

An LCD, or liquid crystal display, is a simple screen that can display commands, bits of information, or readings from your sensor – all depending on how you program your board.

This module is a 20 character by 4 line LCD display with Blue background and White backlight.

The original 2004 LCD needs 7 IO ports to be up and running, ours is built with Arduino IIC/I2C interface, saving you 5 IO ports.

This LCD is ready-to-use because it is compatible with the Arduino Liquid Crystal Library. It comes with EASY Plug connector, you can use one line for simple connection.
