NXT 2.0 Color Sensor

[vstarsal]

I can not get any readings other than 100 for getLightvalue or 1023 for getNormalizedLightValue. It doesn't matter if I expose the sensor to bright light or darkness. I also cannot turn on any LED. I have tried everything I can think of. I have setFloodlight(0) for the red LED, but nothing. I have tried the sensor in SensorPort(S.1) and in S.3, but neither works. I cannot find any code that shows how to get this working. Can you help?

Please post what you've programmed. Could be useful...

Did you test several colour sensors? Maybe your one is broken.

Hi
My most recent code is below.

public static void main(String[] args) {
System.out.println("Press ENTER to begin program.");
Button.ENTER.waitForPressAndRelease();

LightSensor ld = new LightSensor(SensorPort.S3);

ld.setFloodlight(0);
System.out.println("Normal " + ld.readNormalizedValue());
System.out.println("Reg value " + ld.readValue());
System.out.println("Get value " + ld.getLightValue());
System.out.println("Get Normal value " + ld.getNormalizedLightValue());
Button.ENTER.waitForPressAndRelease();
}//end main

But...
I also tried using SensorPort.S1. I also tried using LightDetector and ColorSensor
LightSensor ld = new LightSensor(SensorPort.S1);
LightDetector ld= new ColorSensor(SensorPort.S3);
ColorSensor ld = new ColorSensor(SensorPort.S3);
ld.setFloodlight(true);

If you have the new color sensor you need to use the ColorSensor class not the LightSensor class. LightSensor is for the sensor supplied with the original version of the NXT set...

Take a look at the ColorSensorTest sample application for more details of how you can use this sensor.
