  // then use the "if" command to make LEDs follow these states.

  // Create variables to store the button input values:

  buttonState = digitalRead(buttonPin);
  

  // The if-else statement lets you do different things based on different inputs:

  // The button will read as LOW when it's pressed

  if (buttonState == LOW) // Check to see if buttonState is LOW (pressed) 
  {
    digitalWrite(buttonLED,HIGH); // If buttonState is LOW (pressed), turn on the LED
  }
  else
  {
    digitalWrite(buttonLED,LOW); // If buttonState is HIGH (unpressed), turn off the LED
