सिर्फ LDR और Transistor से बनाएं Auto Light System | Easy DIY

🔌 Automatic Light ON/OFF Using LDR | No Arduino | Simple DIY Electronics Project 🔌 In this video, I’ll show you how to make a simple automatic light control circuit using LDR (Light Dependent Resistor) and a transistor — without using Arduino or any microcontroller! 😍 This project is perfect for beginners who want to learn basic electronics and create a useful home automation system. 📌 What You’ll Learn: How LDR works to detect light How to build a light-sensitive switch using a transistor How to connect an LED or 230V bulb via relay for auto ON/OFF 🧰 Components Used: LDR (Light Dependent Resistor) BC547 Transistor (or any general-purpose NPN) 100k ohm Resistors LED Power Supply (5V/12V depending on the relay) ⚡ Working Principle: When it gets dark, the resistance of the LDR increases, triggering the transistor and activating the light. In daylight, the circuit turns the light off automatically. ✅ No Arduino, No Programming, Just Pure Electronics! 📺 Watch till the end for the full working demo and explanation. --- 🔔 Don’t forget to Like, Share & Subscribe for more DIY Electronics Projects! #LDRProject #AutomaticLight #HomeAutomation #DIYElectronics #NoArduino
