Introduction

Have you ever wondered what cool projects you can build with an LCD (liquid crystal display)? So, The Arduino has communicated with us via sound, via blinking LEDs, and via the Serial Monitor. What would it be like if the Arduino could communicate through a self-contained screen that could display two lines of text at a time? This project is all about using the LCD to display information in characters made of letters, numbers, and a few special symbols. You can make the information scroll and reverse, and you can even do some very simple animations! We start learning about the LCD in Figure 14-1.
