}

void loop()

{     

   

if(Serial.available())

{

count = 0; // Reset the counter to zero

    while(Serial.available() && count < 12)

    {

    input[count] = Serial.read(); 

    count++; // increment counter

    delay(5);

    }

     Serial.println("I received: ");

     for(int i=0;i<12;i++)

     Serial.print(input[i]);

Serial.println();
