Examples |  |
    #include <SoftwareSerial.h>

    int val;
    SoftwareSerial port = SoftwareSerial(8, 9);

    void setup() {
      pinMode(8, INPUT);  // rx pin
      pinMode(9, OUTPUT);  // tx pin
      port.begin(9600);  // Start serial Serial at 9600 baud
    }

    void loop() {
      val = port.read(); // read a value and echo it
      port.print(val);
    }
Description |  | The println() method writes data to the serial port. This is often helpful for looking at the data a program is producing or just to write data to other devices connected to the serial port. The println method works like print, but sends a new line character for each call to the function. Data can either be a single int, float, byte (BYTE), long, char, char[], or a number in decimal (DEC), hexadecimal (HEX) , octal (OCT), or binary (BIN) base.
