新手求助 程式碼的優化

我想要做到按一下就會亮起來,再按就會關掉LED,如些類推,,可是這方法太暴力了,所以想問問有更好的方法嗎
c++沒學好後悔死了......

int PIRSensor = 7;
int ledPin = 13;
int sensorValue = 0;
int ledState = 0;
void setup(){
  Serial.begin(9600);
  pinMode(PIRSensor, INPUT);
  pinMode(ledPin, OUTPUT);
}

void loop(){
  sensorValue= digitalRead(PIRSensor);
  Serial.println(sensorValue);



  if(sensorValue == 1 && count%4==0){
    digitalWrite(ledPin, HIGH);
    count+=;
  }
   if(sensorValue == 0 && count%4==1){
    digitalWrite(ledPin, HIGH);
    count++;
  }
    if(sensorValue == 1 && count%4==2){
    digitalWrite(ledPin, LOW);
    count++;
    }
    if(sensorValue == 0 && count%4==3){
    digitalWrite(ledPin, LOW);
    count++;

}

    }
}

[mw_shl_code=cpp,true]int PIRSensor = 7;

  Serial.println(sensorValue);

  if(sensorValue == 1 ){    delay(50);//去抖
    if(sensorValue == 1 ){
      count=1-count;    }

其实还可以简化，不过可能影响可读性，就算了
