Print data, followed by a carriage return and newline, to the File, which must have been opened for writing. Prints numbers as a sequence of digits, each an ASCII character (e.g. the number 123 is sent as the three characters ‘1’, ‘2’, ‘3’).
file.println() file.println(data) file.print(data, BASE)
file: an instance of the File class (returned by SD.open())
data(optional): the data to print (char, byte, int, long, or string)
BASE(optional): the base in which to print numbers:
BINfor binary (base 2),
DECfor decimal (base 10),
OCTfor octal (base 8),
HEXfor hexadecimal (base 16).
println() will return the number of bytes written, though reading that number is optional
