SoftwareSerial: begin(speed)

Description

Sets the speed (baud rate) for the serial communication. Using speeds higher than 9600 baud will result in faulty communication.

Parameters

speed: the baud rate (long)

Returns

none

Example

// include the SoftwareSerial library so you can use its functions:
#include <SoftwareSerial.h>

#define rxPin 2
#define txPin 3

// set up a new serial port
SoftwareSerial mySerial =  SoftwareSerial(rxPin, txPin);

void setup()  {
  // define pin modes for tx, rx:
  pinMode(rxPin, INPUT);
  pinMode(txPin, OUTPUT);
  // set the data rate for the SoftwareSerial port
  mySerial.begin(9600);
}

void loop() {
  // ...
}
