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: "Your Arduino folder is where all the sketches are stored, and you can define this folder in the preferences of the Arduino IDE."

A block of code is set as follows:

android:textSize="200dp"
    android:gravity="center"

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

/distance
