Conventions

In this book, you will find a number of text styles 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, path names, dummy URLs, user input, and Twitter handles are shown as follows: "We can include other contexts through the use of the include directive."

A block of code is set as follows:

int pin = 13;
void setup() {
 // put your setup code here, to run once:
 pinMode(pin,OUTPUT);
}
void loop() {
 // put your main code here, to run repeatedly:
dot();dot();dot();
dash();dash();dash();
dot();dot();dot();
delay(3000);
}

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "Clicking the Next button moves you to the next screen."

Note
