code:

//no moter //sensor pin const int ldrPin = A1;

//light pin const int ledPin = 13; //speaker pin const int speakerPin = 9;

void setup(){

Serial.begin(115200);
// using those pins as output

pinMode(ledPin, OUTPUT);
pinMode(speakerPin, OUTPUT);

}

void loop() {

 int ldrVal = analogRead(ldrPin);
 //map the value of the light sensor
 ldrVal = map(ldrVal, 170, 600, 0, 1023);
 //constrain the vaule from 0 to 1023
 ldrVal = constrain(ldrVal, 0, 1023);

// turning on the led

 digitalWrite(ledPin, HIGH);

 Serial.println(ldrVal);

 makeTone(ldrVal);

}

void makeTone(int freq){

   digitalWrite(speakerPin, HIGH);
   delayMicroseconds(freq);
   digitalWrite(speakerPin, LOW);
   delayMicroseconds(freq);
