begin()

Description

Sets the data rate in bits per second (baud) for serial data transmission. For communicating with the computer, use one of these rates: 300, 1200, 2400, 4800, 9600, 14400, 19200, 28800, 38400, 57600, or 115200. You can, however, specify other rates – for example, to communicate over pins 0 and 1 with a component that requires a particular baud rate.

 

Syntax

Serial.begin(speed)

 

Parameters

speed: in bits per second (baud) – long

 

Returns

nothing

 

Example:

void setup() {
	Serial.begin(9600);	// opens serial port, sets data rate to 9600 bps
}

void loop() {}
