Arduino Function: SoftwareSerial.available

Description

Get the number of bytes (characters) available for reading from a software serial port. This is data that's already arrived and stored in the serial receive buffer.

Syntax

mySerial.available()

Returns

 the number of bytes available to read

Examples

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

#define rxPin 10
#define txPin 11

// 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() {
if (mySerial.available()>0){
mySerial.read();
}
}
