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.
This module should be used together with EASY plug control board.
