for문과 switch문을 이용해 버튼을 누를때마다 LED의 결과를 다르게 하는건데..여기까지가 한계인것 일까요..ㅠㅠ 혹시 아시는분 있으신가요..3일째인데 깝깝하네요 ㅠㅠ

#define button 12 
#define LED 13 
boolean on = false; 
int buttonCount = 0; 
int programCount = 0;
int buttonState = 0;
void setup() {
  Serial.begin(9600);
  pinMode(LED,OUTPUT); 
  pinMode(button,INPUT_PULLUP);
}
void loop() {
buttonState= digitalRead(button); 
switch( buttonState )
{
  case 1 :
  Serial.println( "Case 1 =>Button");
  digitalWrite(LED, HIGH);
  delay(3000);
  digitalWrite(LED, LOW);
  delay(3000);
  buttonCount++ ;
  programCount++ ;
  break;
  case 2 :
  Serial.println( "Case 2 =>Button");
  digitalWrite(LED, HIGH);
  delay(5000);
  digitalWrite(LED, LOW);
  delay(5000);
  buttonCount++ ;
  programCount++ ;
  break;
  
}
}
