Use the Serial1 port.

-----------------------------------------------------------------------

int waarde = 10;

void setup() {
  Serial1.begin(9600);  //open the TX/RX port
  while (!Serial1) ;     //Specific Leonardo
}

void loop() {
  Serial1.println("test");
  Serial1.print("Value = ");
  Serial1.println(waarde);
}

-----------------------------------------------
