How to Make a Simple Automatic Light Sensor Circuit (BC547, LDR, R100k, LED)

Hey everyone! 👋 In this video, you'll learn how to build a Simple Automatic Light Sensor Circuit using basic electronic components. This project is extremely easy to assemble and perfect for beginners! The LED will automatically turn ON in the dark and turn OFF when light is detected. 🛠️ Components Required: • Transistor BC547 (1x) • Resistor 100kΩ / R100k (1x) • LDR / Light Dependent Resistor (1x) • Red LED (1x) • DC Power Source / Battery (3V - 9V) • Connecting wires & Soldering kit 📌 How It Works: When light hits the LDR, its resistance drops, keeping the base voltage of the BC547 transistor low and the LED turned off. When darkness falls, the LDR's resistance increases sharply, allowing current to flow into the BC547 base, triggering the transistor to automatically turn the LED on!
