Analog light sensor outputs are strange?

Hello all

Ive bought this light sensor module:

Ive put GND to GND, Vcc to 5 v on arduino and signal to A1.

I have uploaded this sketch to it:

int sensorPin = A1;
int lightValue = 0;

// The light sensor 
// the setup routine runs once when you press reset:
void setup() {
  // initialize serial communication at 9600 bits per second:

// the loop routine runs over and over again forever:
void loop() {
  // read the analog input on analog pin 2 (the light sensor):
  lightValue = analogRead(sensorPin);
  // print out the value you read:
  Serial.print("The lightvalue is ");
  delay(500);        // delay in between reads for stability

This results in an output of 221 in the serial monitor. Nothing happens when I put more light onto it or cover it up. When adjusting the potentiometer on the module it jumps at one point to 249.

Any ideas what I am doing wrong?

The photo shows an Electronic Brick with two outputs, one Analog, one Digital and 4 pins.

Which output pin are you connecting to??

I am connected to A0, the analog output.

As I have understood it, the digitaloutput is a on and off pin, which can be adjusted by the potentiometer to set the threshold.

Are you connected to A0 or A1 ? Make up your mind.

In my last post I was referring to the pin on the light module I am connected to.

I am still getting the same results.

Any inputs is much appreciated.
