Conventions used

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_WRITE(V1) // zeRGBa assigned to V1 
{
    // get a RED channel value
int r = param[0].asInt();
    // get a GREEN channel value
int g = param[1].asInt();
    // get a BLUE channel value
int b = param[2].asInt();
}

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: "Under CONTROLLERS, tap zeRGBa. A zeRGBa widget will add on to the canvas."
