Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: “The first section, void setup() {}, holds code that will be run exactly once when the microcontroller boots up.”

A block of code is set as follows:

#include "Display.hpp" 
   void setup() { 
   Display::initialize(); 
   Display::print_lcd("Hello, world", "of embedded"); 
}
void loop() { 
}

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

#include "MyEnv.hpp" 
#include "MyNTPClient.hpp" 
#include <Arduino_MKRENV.h> 
#include <SPI.h> 
#include <SD.h> 

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

mkdir MyAPI
cd MyAPI

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “Click on Install, below the library provided by DFRobot.”
