		String^ num = textBox2->Text;

		return;
	}

		SerialPort port("COM9", 9600);
		port.Open();
		while (true)

			for (int i = 0; i < 3; i++)
			{
				textBox1->Text += numbers[i].ToString() + " ";
				port.Write(textBox1->Text);
				mStr = port.ReadLine();
				if (counter != 0)
					textBox2->Text += mStr;
			}
			if (counter == 0)
				counter = 1;
			else
				counter = 0;
			
			if (dec_value >= 100000)
				port.Write("A");
			else if (dec_value < 100000)
				port.Write("B");
			else
				port.Write("C");
				
			return;
		}
	}


The purpose is I want to control LED based the value of "dec_value" but it doesn't work

And the arduino program is like this:

#include <Eeprom24Cxx.h>

static Eeprom24C eeprom(4, 0x50);
int i =0;
long valueCounterAll= 0;

void setup() 
{ 
  pinMode(ledRed, OUTPUT);
  pinMode(ledGreen, OUTPUT);
  pinMode(ledBlue, OUTPUT);

  digitalWrite(ledRed, LOW);
  digitalWrite(ledGreen, LOW);
  digitalWrite(ledBlue, LOW);
  
  Serial.begin(9600);
}

void loop() 
{
  if (Serial.available())
  {
    i = Serial.parseInt();
    byte data = eeprom.read_1_byte(i);
    for (int i = 0; i < 8; i++)
    {
      Serial.print(bitRead(data, 7 - i));
    }
    Serial.println("");
  }

  if(valueCounterAll>=10000000)
    {
      digitalWrite(ledRed, HIGH);
      digitalWrite(ledGreen, LOW);
      digitalWrite(ledBlue, HIGH);
    }
    else if (valueCounterAll<10000000)
    {
      digitalWrite(ledRed, LOW);
      digitalWrite(ledGreen, HIGH);
      digitalWrite(ledBlue, HIGH);
    }
    else
    {
      digitalWrite(ledRed, HIGH);
      digitalWrite(ledGreen, HIGH);
      digitalWrite(ledBlue, LOW);
    }
}

Is there help, anyone ?

On line 29 of the arduino program you read an int using parseInt(). While in you pc program you send the letters "A", "B" and "C". What does i contain after Serial.parseInt()?

Also you never change valueCounterAll at all. And how will the thiird else on line 50 ever be processed?
