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: "This will un-archive a set of files and directories under the arduino-1.5.3-Intel.1.0.3 directory structure."

A block of code is set as follows:

qData = false; // Initialize on reset
gSerialStdPtr->begin(9600); // Receiver
gSerialTwoPtr->begin(9600); // Sender
waitForUser(5); // Give usr time to open serial terminal
gSerialStdPtr->println("XBee-Receiver-setup");
pinMode(led, OUTPUT);

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

mv maestro-linux-100507.tar.gz?file_id=0J315 maestrolinux-100507.tar.gz

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: "Select the Start | Control Panel | Device Manager inside Windows."
