🚀🔧 Project Spotlight: Smart Lamp

🎯 Objective

To make a Smart Lamp by using Arduino UNO microcontroller and LDR(Light Dependent Resistor), where we are controlling an LED based on intensity of light..

📋 Project Description

This project involves creating a Smart Lamp utilizing an Arduino UNO microcontroller paired with a Light Dependent Resistor (LDR). The main objective is to develop an intelligent lighting system that automatically turns on and off an LED based on the ambient light intensity in the environment.

💡 Prerequisites

These are the prerequisites for making Smart Lamp Project:

• Basic knowledge of Arduino UNO and LDR sensors.

• Familiar with the Block coding, TinkerCAD and Arduino IDE.

⚙️ Required Components

🧪 How It Works

The Smart Lamp functions through the integration of electronic components and simple programming logic that allow it to respond to environmental light conditions automatically. Here's a breakdown of how it works:

1. Light Detection with LDR: The lamp uses a Light Dependent Resistor (LDR) sensor to detect ambient light levels. The LDR's resistance changes based on the amount of light falling on it—lower resistance in bright light and higher resistance in darkness.

   
   

2. Microcontroller Processing: An Arduino (or similar microcontroller) reads the input from the LDR and processes it based on a predefined threshold set in the code. If the ambient light drops below this threshold, the microcontroller knows it’s time to turn on the lamp.

   
   

3. Automatic Lighting Control: When the microcontroller determines that it's dark enough, it sends a signal to power the LED or bulb, turning the lamp on. When ambient light returns, the lamp turns off—mimicking how smart lighting works in energy-efficient homes.

   
   

4. User Customization: The logic can be customized using code to change the light threshold, add delays, or even include features like blinking or dimming.

   
   

5. Optional Power Control: The lamp may be powered by batteries, a USB cable, or a wall adapter, depending on the build. Students can explore different powering methods to understand energy consumption.

   
   

This simple yet impactful mechanism introduces students to key concepts such as sensor data, conditional statements, and automation—all while building a practical and interactive device.
