I am new to Arduino programming and I would like to ask a question.

Firstly apologies if this has been answered before and I understand if it gets locked if this has been answered elsewhere.

I am trying to get three LED's (red, amber, green) to loop 5 times (in a do loop).

for this I have created a integer variable (x) and initialised the variable to 0.

I then increase x by 1 each time.

However I cannot get them to stop looping when x is greater than 5. The program does work as expected for everything else (green LED lit, wait 1 sec, Yellow LED lit, wait 1 sec, red LED lit and then loop).

   //set LED pins
int greenPin = 13;
int yellowPin = 12;
int redPin = 11;

void setup()
{
  pinMode(greenPin, OUTPUT);      // sets the digital pin as output
  pinMode(yellowPin, OUTPUT);
  pinMode(redPin, OUTPUT);
}

void loop(){
int x = 0;

 do {
  digitalWrite(greenPin, HIGH);   // sets the LED on
  delay(1000);                  // waits for a second
  digitalWrite(greenPin, LOW); 
  digitalWrite(yellowPin, HIGH);    // sets the LED off
  delay(1000);
  digitalWrite(yellowPin, LOW);// waits for a second
  digitalWrite(redPin, HIGH);    // sets the LED off
  delay(1000);
  digitalWrite(redPin, LOW);
 }
   while(x<=5); {
    x = x + 1;
   }
}
