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

SoftwareSerial serial(6, 7);

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