Circuit Theory
Example 14-1 displays a variety of characters, letters, and numbers based on C language programming instructions. The sketch is programmed to test all segments of the LCD as it cycles through the Arduino program. The Arduino sketch uses digital data pins D2, D3, D4, D5, D11, and D12 of its microcontroller chip to send text message information to…

Upload the LCD News Reader Sketch
It’s time to upload the sketch for the LCD News Reader to the Arduino. Here are the steps you’ll need to follow: Once the LCD News Reader sketch has been uploaded to the Arduino, the LCD will display a message, as shown in Figure 14-1. According to computing tradition, the first message you should display on a…

Let’s Build the LCD
The first task in building the LCD News Reader is to solder a 16-pin male header to the LCD. The header needs to be cut to a length to match the 16 LCD copper pad holes. Figure 14-2 shows the male header cut to the appropriate LCD length. Insert the 16-pin male header through the copper pad holes and…

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…
