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);
