Project Introduction

---

Here is an arduino uno tutorial combined with TCS230 color sensor. TCS230 serves as a color reader and removes the color that is read into the LED. When the prototype in the run we simply put something on the sesor object and directly LED issued the same color with the color of the object.

Component Description

---

Arduino Uno - is a Atmega32-based microcontroller board. Having many digital and analog pins, the arduino can be easily programmed via a computer or laptop with USB and is designed to facilitate electronic users in various fields. As open source he comes with 2 products namely Hardware Arduino Board and Arduino IDE software.

TCS230 Module - is a color sensor that is often used in microcontroller applications including arduino uno for the detection of an object object or color of the objet on the monitor. TCS230 has 8 pin, 2 pin GND (-), 2 pin VCC (+), Pin S0, 1 Pin S1, Pin S2, Pin S3, LED pin, and Pin OUT. The TCS230 senses the color light with the help of an 8 x 8 array of photodiodes.

You can buy from online store or directly to the Electronics Shop

Step 2 : Build Circuit Architecture

• Connect the GND and VCC

---

• Connect Pin GND Arduino Uno to GND TCS230
• Connect Pin 5V Arduino Uno to VCC TCS230

---

• Pin Connect

• Connect the "pin number 7" of the arduino uno board to "S2" TCS230.
• Connect the "pin number 6" of the arduino uno board to "S3" TCS230.
• Connect the "pin number 5" of the arduino uno board to "S1" TCS230.
• Connect the "pin number 4" of the arduino uno board to "S0" TCS230.

---

• Out Connect

• Connect the "pin number 8" of the arduino uno board to "OUT" TCS230.

Step 3 : Programing

---

• Connect Arduino to the computer with USB .

• Open the Arduino IDE > Chose your Board Type
  

• first Define Variable #define

#define SEN0 5
#define SEN1 4
#define SEN2 7
#define SEN3 6
#define senOutput 8

int frequency = 0;

• After Define you Now Set Up the All PinMode void setup()

void setup() {
  Serial.begin(9600);
  pinMode(SEN0, OUTPUT);
  pinMode(SEN1, OUTPUT);
  pinMode(SEN2, OUTPUT);
  pinMode(SEN3, OUTPUT);
  pinMode(senOutput, INPUT);

Setting frequency-scaling to 20%

 digitalWrite(SEN0,HIGH);
 digitalWrite(SEN1,LOW);
}

• Last program in void loop() everything about the system can be run

• Setting red filtered photodiodes to be read

digitalWrite(SEN2,LOW);
digitalWrite(SEN3,LOW);

Reading the output frequency

frequency = pulseIn(senOutput, LOW);

Remaping the value of the frequency to the RGB Model of 0 to 255

frequency = map(frequency, 25,72,255,0);

Printing the value on the serial monitor

Serial.print("R= ");//printing name
Serial.print(frequency);//printing RED color frequency
Serial.print("  ");
delay(100);

• Setting Green filtered photodiodes to be read

  digitalWrite(SEN2,HIGH);
  digitalWrite(SEN3,HIGH);

Reading the output frequency

  frequency = pulseIn(senOutput, LOW);

Remaping the value of the frequency to the RGB Model of 0 to 255

    frequency = map(frequency, 30,90,255,0);

Printing the value on the serial monitor

  Serial.print("G= ");//printing name
  Serial.print(frequency);//printing RED color frequency
  Serial.print("  ");
  delay(100);

• Setting Blue filtered photodiodes to be read

  digitalWrite(SEN2,LOW);
  digitalWrite(SEN3,HIGH);

Reading the output frequency

  frequency = pulseIn(senOutput, LOW);

Remaping the value of the frequency to the RGB Model of 0 to 255

  frequency = map(frequency, 25,70,255,0);

Printing the value on the serial monitor

  Serial.print("B= ");//printing name
  Serial.print(frequency);//printing RED color frequency
  Serial.println("  ");
  delay(100);

After write codes, click the "Verify button" to save and compile the sketch. This will also check for any errors in the program.

If no errors is found , now you can click "Upload button" to start installing the program into the arduino uno board.
