🌟 Smart Street Lighting System Using Arduino and LDR

🔍 Overview

This project is a simple and efficient Smart Street Lighting System using Arduino and an LDR. It automatically controls street lights based on ambient light.

🎯 Objective

Build a system that turns lights ON at night and OFF during the day using Arduino and LDR.

🧠 How It Works

The LDR senses light levels. When it gets dark, the Arduino turns the light ON. In daylight, the light is OFF.

🧰 Components Used

• Arduino UNO
• LDR Sensor
• 10kΩ Resistor
• LED / Relay module
• Jumper wires, Breadboard

💻 Arduino Code

int ldrPin = A0;
int lightPin = 13;
int threshold = 500;

void setup() {
  pinMode(lightPin, OUTPUT);
  Serial.begin(9600);
}

void loop() {
  int ldrValue = analogRead(ldrPin);
  Serial.println(ldrValue);

  if (ldrValue < threshold) {
    digitalWrite(lightPin, HIGH);
  } else {
    digitalWrite(lightPin, LOW);
  }

  delay(500);
}
