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: "In the loop() function, we read the value of the distance from the sensor and then display it on the serial port."

A block of code is set as follows:

void loop() {   int val;   val = analogRead(A0);      Serial.print("Soil moisture: ");   Serial.print(val);    delay(3000); } 

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

 $ sudo apt-get update
 $ sudo raspi-config
