Arduino program to turns on LED when the button is pressed once and remains on until the button is pressed again to turn it off

int buttonState = 0;        // Variable to store the current button state
int lastButtonState = 0;    // Variable to store the previous button state
int ledState = LOW;         // Variable to store the LED state (initially off)

void setup() 
{
  // Initialize the LED pin as an output
  pinMode(13, OUTPUT);
  // Initialize the push button pin as an input
  pinMode(2, INPUT);
}

void loop() {
  // Read the current state of the push button
  buttonState = digitalRead(2);
  // Check if the button state has changed from the last loop
  if (buttonState != lastButtonState) 
  {
    // If the button state is HIGH (pressed)
    if (buttonState == HIGH) 
    {
      // Toggle the LED state
      ledState = !ledState;
      // Update the LED pin with the new state
      digitalWrite(13, ledState);
    }
    // Delay for debouncing
    delay(50);
  }
  // Save the current button state as the last state for the next loop
  lastButtonState = buttonState;
}
