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… Continue reading Circuit Theory

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… Continue reading Let’s Build the LCD

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… Continue reading Introduction
