Color sensor for Arduino?

Using Arduino Sensors
1

Hi
i'm not very good at electronic and Arduino
i want to connect my arduino to a color sensor that can detect the 7 basic colors
so what is the best color sensor for arduino to work with it??
Please someone answer me

no need buying you can make your own, place a photoresistor next to a rbg leds or 3 leds and then measure which is higher, then you will find out ! here code:

EDIT: sorry didn't realize its 2 years old !

int CN[3]; // holds each color result
int avarage;
int blue = 11, green = 10, red = 9; // just to dont get messy !
int GV = 36 ,RV = 67 ,BV = 97;

int ARsure();

void setup(){
  Serial.begin(9600);
  
  pinMode(blue,OUTPUT);
  pinMode(green,OUTPUT);
  pinMode(red,OUTPUT);
  
   //Starts Blue Calibrating
  BV = 100;
  analogWrite(blue,BV);
  while(ARsure() != 100){
    if(avarage > 100){
      BV--;
    } else if (avarage < 100) {
      BV++;
    }
    analogWrite(blue,BV);
  }
  
  digitalWrite(blue,LOW);
  //Blue end
  GV = 100;
  analogWrite(green,GV);
  while(ARsure() != 100){
    if(avarage > 100){
      GV--;
    } else if (avarage < 100) {
      GV++;
    }
    analogWrite(green,GV);
  }
  
   digitalWrite(green,LOW);
  //Green end
  
  RV = 100;
  analogWrite(red,RV);
  while(ARsure() != 100){
    if(avarage > 100){
      RV--;
    } else if (avarage < 100) {
      RV++;
    }
    analogWrite(red,RV);
  }
  
   digitalWrite(red,LOW);
  //Red end
  
}

void loop(){
  analogWrite(green,GV);
  delay(15);
  
  avarage = 0;
  for(int i = 0;i<10;i++){
    avarage += analogRead(0);
    delay(15);
  }
  CN[0] = avarage/10;
  digitalWrite(green,LOW);
  
  //end
  
  analogWrite(blue,BV);
  delay(15); // delay for RBG LED to get its full brightness 
  
  avarage = 0;
  for(int i = 0;i<10;i++){
    avarage += analogRead(0);
    delay(15);
  }
  CN[1] = avarage/10; // reads photoresistor while the blue led is on (must see more light if object is blue);
  digitalWrite(blue,LOW); // turn off for next color
  
  //end
  
  analogWrite(red,RV);
  delay(15);
  
  avarage = 0;
  for(int i = 0;i<10;i++){
    avarage += analogRead(0);
    delay(15);
  }
  CN[2] = avarage/10;
  digitalWrite(red,LOW);
  
  if(CN[0] > CN[1] && CN[0] > CN[2]){
    Serial.println("Green!");
  } else
    if(CN[1] > CN[0] && CN[1] > CN[2]){
     Serial.println("Blue!");
    } else {
    if(CN[2] > CN[0] && CN[2] > CN[1]){
      Serial.println("Red!");
    }
  }
  Serial.print("Green: ");
  Serial.println(CN[0]);
  Serial.print("Blue: ");
  Serial.println(CN[1]);
  Serial.print("Red: ");
  Serial.println(CN[2]);
  Serial.println(" ------------------- END");
  
  
  delay(2000); // time to read and think ! 
}

int ARsure(){
  avarage = 0;
  for(int i=0;i<8;i++){
      delay(1);
      avarage += analogRead(0);
    }
    
    avarage = avarage / 8;
    //Serial.println(avarage);
    return avarage;
}

hi,

i have a color sensor TSC230, but i don't know how to calibrate this one
to recognize a RGB color, i also have a AT MEGA Microprocessor,

Pls help me,
Thanks a lot, God Bless.

I doubt anyone knows how to use the TSC230.

Its suppose to be a Color RGB sensor, but as far as i can tell it is able to distinct red from blue, and often green. and thats about it. Forget rainbow-grade detection. I mean, that thing is in-accurate as * if the 101 examples i tried, are supose to work for it...

If you are looking for TCS230 library that works with an explanation of how to calibrate the sensor, look at my code libraries, linked below.

Good Day Sir...

I 'm working on a project on color detection using TSC3200 Color Sensor...
How can I configure the TSC3200 to detect the exact frequencies of the RGB color?
How can i determine the exact frequencies of the RGB color?..

I already done the 80 - 85% of the program of the color sensor... The problem is when I put red, blue or green objects we got the same frequency...

Thank Sir..
