Using the NXT Color Sensor with EV3

[Auctor137]

Hey there,

the last two hours I’ve tried to get the NXT Color Sensor to read some colors, but it didn’t work so well. I
The program below prints for each color a “1”. I’ve tried using the other possibilities:
ReadAsString() – prints an “Black” for each color
Read() – prints an “1”

and ReadRGB.. well, how do i save it ? Won’t work with int, byte, string, char… ?

using System;
using System.Threading;
using MonoBrickFirmware.Sensors;
using MonoBrickFirmware.Movement;
using MonoBrickFirmware.Display;
using MonoBrickFirmware.UserInput;

namespace AMotorcolor
{
    class Program
    {
        static void Main(string[] args)
        {
            NXTColorSensor sens = new NXTColorSensor(SensorPort.In1);
            Motor motorA = new Motor(MotorPort.OutA);
            
            int farbe1, farbe2;     
                                 
            LcdConsole.WriteLine("Scanne Farbe 1..."); // reading the first color
            Thread.Sleep(500);
            farbe1 = sens.ReadRaw();
            LcdConsole.WriteLine("Farbe 1 = " + farbe1);
            Thread.Sleep(4000);

            LcdConsole.WriteLine("Scanne Farbe 2..."); // reading the second color
            Thread.Sleep(500);
            farbe2 = sens.ReadRaw();
            LcdConsole.WriteLine("Farbe 2 = " + farbe2);
            Thread.Sleep(4000);
                     
            
            LcdConsole.WriteLine("PROGRAMMENDE...");
            Thread.Sleep(1000);
            motorA.Off();
        }
    }
}

Thanks in advance..

Hi there

Use the color sensor example from Git and replace the EV3Color sensor with the NXTColor sensor. Also have a look at the documentation for the NXT color sensor found here…

…

I’ve used the NXT LIGHTsensor, not the COLORsensor.
Oh man.

Tho you can still read it with “ReadRaw ()” and “Read ()”. It just won’t return colors but light intensity in percent.

Yeah I know, but i need to read the colors. I’ve used the EV3 Colorsensor now and it works fine.
