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(6, 7);
int analogValue;

void setup()
{
  serial.begin(9600);
}

void loop()
{
  // read the analog input on pin 0:
  analogValue = analogRead(0);

  // 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);
}
