ifelse小練習

int inputNumber = -1;
void setup() {
  pinMode(LED_BUILTIN, OUTPUT);     // Initialize the LED_BUILTIN pin as an output
  Serial.begin(9600);
}

void loop() {
  if(Serial.available()){
    inputNumber = Serial.parseInt();//接收序列埠監控視窗的數字
    if(inputNumber >= 50){
        Serial.print("您輸入的數字是：");
        Serial.println(inputNumber);
        digitalWrite(LED_BUILTIN, LOW);//燈亮   
        Serial.println("led on");
        delay(1000);
     }else{
        Serial.print("您輸入的數字是：");
        Serial.println(inputNumber);
        digitalWrite(LED_BUILTIN, HIGH);//燈滅
        Serial.println("led off");
        delay(2000);
     }
   }else{
      Serial.println("waiting your input");
      delay(1000);
    }
