Conventions

In this book, you will find a number of styles of text that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "In the setup() function of the sketch, we will try to get an IP address using DHCP."

A block of code is set as follows:

String log_time = String(day()) + "/" + 
String(month()) + "/" + String(year()) + " " + 
String(hour()) + ":" + String(minute()) + ":" + 
String(second());

Any command-line input or output is written as follows:

# 192.168.1.103/digital/7/1

New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: "If you are using Windows, you will find the information you need under Network Settings in your Control Panel."
