Experiment No. 4
Aim: To design an automatic night lamp using LDR.
Apparatus: ARDUINO, LDR, Resistance 10k ohm, wires, Breadboard
Theory: IT senses the light intensity from surroundings and find whether its day or
night.
Programming:
void setup()
{
Serial.begin (9600);
pinMode(7,OUTPUT);
}
void loop()
{
int c = analogRead(A0);
Serial.println(c);
If (c<850)
{
digitalWrite(7,LOW);
}
else
{
digitalWrite(7,HIGH);
}
}
