Arduino Function: SoftwareSerial Constructor


A call to SoftwareSerial(rxPin, txPin) creates a new SoftwareSerial object, whose name you need to provide as in the example below. You need to call SoftwareSerial.begin() to enable communication.


  • rxPin: the pin on which to receive serial data
  • txPin: the pin on which to transmit serial data


#define rxPin 2
#define txPin 3

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