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);
