ArduinoSoftwareSerial.begin()
Sets the speed (baud rate) for the serial communication. Supported baud rates are: 300, 600, 1200, 2400, 4800, 9600, 14400, 19200, 28800, 31250, 38400, 57600, and 115200 bauds.
Syntax
mySerial.begin(speed)Parameters
- speed: the desired baud rate (long). Supported baud rates are: 300, 600, 1200, 2400, 4800, 9600, 14400, 19200, 28800, 31250, 38400, 57600, and 115200 bauds.
Returns
None.
Example
#include <SoftwareSerial.h>
#define rxPin 10
#define txPin 11
// Set up a new SoftwareSerial object
SoftwareSerial mySerial = SoftwareSerial(rxPin, txPin);
void setup() {
// Define pin modes for TX and RX
pinMode(rxPin, INPUT);
pinMode(txPin, OUTPUT);
// Set the baud rate for the SoftwareSerial object
mySerial.begin(9600);
}
void loop() {
// ...
}
