Photoresistor by BARRAGAN
Reads values from a photoresistor connected to the analog input pin 0. The value read from the sensor is proportional to the amount of light that hits the sensor surface. The value read is printed through the serial to be monitored in the console.

    int val;

    void setup()
    {
      Serial.begin(9600);      // sets the serial port to 9600
    }

    void loop()
    {
      val = analogRead(0);     // read analog input pin 0
      Serial.print(val, DEC);  // prints the value read
      Serial.print(" ");	   // prints a space between the numbers
      delay(100);              // wait 100ms for next reading
    }
