Product description
Introduction
2004 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.
This module carries I2C interface, so we need to comply with I2C protocol in usage and corresponding head files must be included and added into the library.
