Problem with QTR-1RC digital sensor

ok so here is my problem:

i have managed to get reading from the sensor, i made it so i can read 0 when white and 1 when black

the problem is on the serial monitor i get an extra value on the end of the value which is 8224 and a 0 and i do not know why…

this is my code:

#include <QTRSensors.h>


#define NUM_SENSORS   1     // number of sensors used
#define TIMEOUT       2500  // waits for 2500 microseconds for sensor outputs to go low
#define EMITTER_PIN   2     // emitter is controlled by digital pin 2

QTRSensorsRC qtrrc((unsigned char[]) {3},
  NUM_SENSORS, TIMEOUT, EMITTER_PIN); 
unsigned int sensorValues[NUM_SENSORS];


void setup ()
{
  delay(500);
  int i;
  pinMode(13, OUTPUT);
  digitalWrite(13,HIGH);
  for (i=0; i < 400; i++)
  {qtrrc.calibrate();
  }
  digitalWrite(13,LOW);
  
  Serial.begin(9600);
  for (i=0; i < NUM_SENSORS; i++)
  {Serial.print(qtrrc.calibratedMinimumOn[i]);
  Serial.print('  ');
  }
  Serial.println();
  
  for (i=0; i<NUM_SENSORS; i++)
  {Serial.print(qtrrc.calibratedMaximumOn[i]);
  Serial.print('  ');
  }
  Serial.println();
  Serial.println();
  delay(1000);
}

void loop()
{
  unsigned int position = qtrrc.readLine(sensorValues);
  unsigned char i;
  for (i=0; i<NUM_SENSORS; i++)
  {Serial.print(sensorValues[i]/1000);
  Serial.print('  ');
  }
  Serial.print("    ");
  Serial.println(position);
  
  delay(250);
}

and this is what i get on the serial monitor:

any help will be much apreciated …

thanks

please post code between code tags - it is the # button above the smileys

one error

void loop()
{
  unsigned int position = qtrrc.readLine(sensorValues);

  unsigned char i;
  for (i=0; i<NUM_SENSORS; i++)
  {
    Serial.print(sensorValues[i]/1000);  //  you forgot the index here
    Serial.print('  ');
  }
  Serial.print("    ");
  Serial.println(position);
  
  delay(250);
}

oups... yes sorry... done and ... it was because i didn't put it in the code thing that it somehow didn't write the index when i copied... but it is there...

i have also added a second sensor and it still shows me that 8224 .. now it shows me that after the reading from the second sensor as well

anyone else know anything?
