Question

For school I’m building a robot, which needs to be able to detect lines using 3 QRE1113 linesensors. (http://www.sparkfun.com/products/9454) I created 4 libraries, two for driving (Motor() & Driver()) they work fine. Now I created the libraries Linesensor and Eye, these are causing some trouble. When I want to use these libraries, the setup() function won’t do squad. Not even turn a LED on. What seems to be the problem?

Main file:

#include "Motor.h"
#include "Driver.h"
#include "Lichtsensor.h"
#include "Eye.h"

Motor motor1(5, 4, true);
Motor motor2(6, 7, false);
Driver driver(motor1, motor2);
Eye eye1;

void setup(){
  pinMode(13, OUTPUT);
  digitalWrite(13, HIGH);
  Serial.begin(9600);
  Serial.println("#################################################");
  Serial.println("# This sketch communicates with the arduino and #");
  Serial.println("# makes the robot drive, and react to a sensor. #");
  Serial.println("#################################################\n");
}

void loop(){
  if (eye1.getDikkeLijn() == true) {
      Serial.println("Lijn");
    }
   else {
     Serial.println("Niks");
   }
  delay(1000);
}

Eye library:

/*
Controls Lichtsensors
*/
#ifndef Eye_h
#define Eye_h

#include "Arduino.h"
#include "Lichtsensor.h"

class Eye 
    public:
    Eye();
    Eye(Lichtsensor l1, Lichtsensor l2, Lichtsensor l3);
    boolean getDikkeLijn();
    boolean getDunneLijn();
private:
    Lichtsensor _l1;
    Lichtsensor _l2;
    Lichtsensor _l3;
};

#endif

And the linesensor:

/*
Library to get values from a light sensor
*/
#ifndef Lichtsensor_h
#define Lichtsensor_h

#include "Arduino.h"

class Lichtsensor {
public:
    Lichtsensor();
    Lichtsensor(int analogPin);
    int getCalibreerWaarde();
    int getLichtWaarde();
    boolean isDonker();
private:
    int _lichtCalibreerWaarde;
    int _analogPin;
};

#endif

It looks like we had too many classes and the arduino couldn’t handle it anymore.
