Printing Binary

Overview

By default, the print command prints numbers in decimal. By adding a second argument to the print command, you can print numbers in binary.

Serial.print(6);                //this will print 6

Using an optional argument you can specify alternative base representations.

Serial.print(7, DEC);        //this will print 7

Serial.print(7, BIN);        //this will print 111
