How can I light one led from two different sensors?

Question

I want to light one led with two sensors, the first one is a PIR and the other one is a Photocell sensor.

The idea is to turn on the led if the PIR sensor detects movement, and also to turn the led on if the room gets darker(detected by the photocell).

I managed to make a code, but with TWO led's, a different one for every sensor.

int ledPin = 13; 
int ledPin1=12;  
const int ldrPin = A0;             
int inputPin = 2;               
int pirState = LOW;             
int val = 0; 


void setup() {
  Serial.begin(9600);
  pinMode(ledPin, OUTPUT);
  pinMode(ledPin1, OUTPUT);
  pinMode(inputPin, INPUT);
  pinMode(ldrPin, INPUT);
}

void loop() {

  int ldrStatus=analogRead(ldrPin);
   if(ldrStatus<=400)
 {
    digitalWrite(ledPin, HIGH);
    delay(500);
    Serial.println("LED ON");
 }
   else digitalWrite(ledPin, LOW);
    val = digitalRead(inputPin); 
      if (val == HIGH) {          
        digitalWrite(ledPin1, HIGH);  
          if (pirState == LOW) {
            Serial.println("Motion detected!");
            pirState = HIGH;
         }
      } else {
          delay(5000);
          digitalWrite(ledPin1, LOW);
            if (pirState == HIGH){
             Serial.println("Motion ended!");
             pirState = LOW;
           }
     }
  }

Answer 1

int ledPin = 13;

int ldrPin = A0;

int PIR_Pin = 2; 

void setup() 

{  

    Serial.begin(115200);

    pinMode(ledPin, OUTPUT);

    pinMode(PIR_Pin, INPUT); 


    Serial.println("Started Monitoring!");
} 

void loop() 
{ 


    boolean lightStatus = ( analogRead(ldrPin) <= 400 ) ;
    digitalWrite(ledPin,  lightStatus);

    if(lightStatus) Serial.println("Light Triggered!");

    if(digitalRead(PIR_Pin) == LOW)
    {
         Serial.println("Motion Triggered!");
         digitalWrite(ledPin, HIGH);
         delay(5000);
         digitalWrite(ledPin, LOW);
     }
}

To keep it simple serial code is removed, if needed can be added easily that should not be a big issue. Still this can be done in much more efficient way. This is just one solution.

Note: haven't complied/error checked the code as i am writing this on a phone. Hope it should work as intended, errors if any, shall be minor ones. Comment below if any issues.

Update 1: added code to send triggered status over serial comm.

Update 2: corrected "Boolean" to be as "boolean"
