## SoftwareSerial: println(data)

#### Description

Prints data to the transmit pin of the software serial port, followed by a carriage return and line feed. Works the same as the Serial.println() function.

#### Parameters

vary, see Serial.println() for details

#### Returns

byte
println() will return the number of bytes written, though reading that number is optional

#### Example

SoftwareSerial serial(10,11);
int analogValue;
void setup()
{
serial.begin(9600);
}
void loop()
{
// read the analog input on pin 0:
analogValue = analogRead(A0);
// print it out in many formats:
serial.print(analogValue); // print as an ASCII-encoded decimal
serial.print("\t"); // print a tab character
serial.print(analogValue, DEC); // print as an ASCII-encoded decimal
serial.print("\t"); // print a tab character
serial.print(analogValue, HEX); // print as an ASCII-encoded hexadecimal
serial.print("\t"); // print a tab character
serial.print(analogValue, OCT); // print as an ASCII-encoded octal
serial.print("\t"); // print a tab character
serial.print(analogValue, BIN); // print as an ASCII-encoded binary
serial.print("\t"); // print a tab character
serial.print(analogValue/4, BYTE); // print as a raw byte value (divide the
// value by 4 because analogRead() returns numbers
// from 0 to 1023, but a byte can only hold values
// up to 255)
serial.print("\t"); // print a tab character
serial.println(); // print a linefeed character
// delay 10 milliseconds before the next reading:
delay(10);
}
