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

CodeInText: 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: "Mount the downloaded WebStorm-10*.dmg disk image file as another disk in your system."

A block of code is set as follows:

Blynk.begin(auth, ssid, pass); //This will start the Blynk with proper credentials
pinMode(4, OUTPUT); //for trigger in D1
pinMode(5, INPUT); //for echo in D2

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "Click on New Project, and name your project anything you want."
