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, pathnames, 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:

//Variable to store the pin
int ldrSensor = 10;

void setup(){
//Start the serial communication
  Serial.begin(9600);
}

void loop(){
//Save the data from the sensor into storeData
  int storeData=analogRead(ldrSensor);
//Re-map storeData to a new range of values
  int mapValue=map(storeData,130,430,0,2000);
//Print the re-mapped value
  Serial.println(mapValue);
//Give the computer some time to print
  delay(200)
}

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."
