Example code

```
#include <SoftwareSerial.h>

SoftwareSerial bluetooth(2, 3); // RX, TX

void setup() {
  Serial.begin(9600);
  bluetooth.begin(9600);
}

void loop() {
  if (Serial.available()) {
    bluetooth.write(Serial.read());
  }
  if (bluetooth.available()) {
    Serial.write(bluetooth.read());
  }
}
```
