All digital pins support software serial, but using pins from different port groups can improve performance. void loop() mySerial.println("Hello")
If the sketch compiles without errors, the library is correctly installed. 6.1 Basic Initialization SoftwareSerial ss(RX_PIN, TX_PIN); ss.begin(baudRate); 6.2 Sending Data Use write() , print() , println() , write(uint8_t) , etc.
