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 loop() function, we first print the half Christmas tree."

A block of code is set as follows:

if (logFile) {
    logFile.print(val1); // Write first value
    logFile.print(" "); // Write a space
    logFile.println(val2); // Write second value
    logFile.close(); // close the file
  }

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: " To easily find information about a card, run the Arduino IDE built-in example found under File | Examples | SD | CardInfo."
