Prints a data to the serial port, followed by a carriage return character(ASCII 13, or '\r') and a newline character (ASCII 10, or '\n'). This command takes the same forms as Serial.print():
Serial.println(b) prints b as a decimal number in an ASCII string followed by a carriage return and a linefeed.
Serial.println(b, DEC) prints b as a decimal number in an ASCII string followed by a carriage return and a linefeed.
Serial.println(b, HEX) prints b as a hexadecimal number in an ASCII string followed by a carriage return and a linefeed.
Serial.println(b, OCT) prints b as an octal number in an ASCII string followed by a carriage return and a linefeed.
Serial.println(b, BIN) prints b as a binary number in an ASCII string followed by a carriage return and a linefeed.
Serial.print(b, BYTE) prints b as a single byte followed by a carriage return and a linefeed.
Serial.println(str) if str is a string or an array of chars, prints str an ASCII string.
Serial.println() just prints a carriage return and a linefeed.
b: the byte to print, or
str: the string to print
None
