ARDUINO COUNTER USING IR SENSOR FC-51

arduino counter using IR sensor FC-51 is for use at bathroom or toilet
for counting people in and out, if the counter is zero, then it will turn off the light



#define in 5
#define out 7
#define relay 2
#define power 9
int pinIn;
int pinOut;
int statusIn= 0;
int statusOut;
int count=0;
void IN()
{
    count++;
    //Serial.println(count);
    delay(1000);
}
void OUT()
{
  count--;
  //Serial.println(count);
  delay(1000);
}
void setup()
{
  Serial.begin(9600);
  delay(2000);
  pinMode(in, INPUT);
  pinMode(out, INPUT);
  pinMode(relay, OUTPUT);
  pinMode(power, OUTPUT);
  digitalWrite(power, HIGH);
}
void loop()
{
    Serial.println(count);
    //ada halangan 0
    pinIn = digitalRead(in);
    if(statusIn == 0 && pinIn == 0 && pinOut == 0){
      IN();
      statusIn = 1;
    }
    if(statusIn == 1 && pinIn == 1){
      statusIn =0;
    }

    pinOut = digitalRead(out);
    if(statusOut == 0 && pinOut == 0 && pinIn == 0){
      OUT();
      statusOut = 1;
    }
    if(statusOut == 1 && pinOut == 1){
      statusOut =0;
    }
}
