Dark Sensor Circuit Using LDR & Transistor (Electronics base Project)

In this video, I demonstrate how to build a simple dark sensor circuit using an LDR and a transistor. This circuit automatically turns ON an LED in the dark and turns it OFF in the presence of light. This is a beginner-friendly electronics project and does not require an Arduino or any programming. What you’ll learn in this video: How an LDR (light sensor) works How a transistor acts as a switch Designing a dark-controlled circuit Building an automatic dark system without a microcontroller Some applications of this project: Automatic street lights Smart home lighting systems Energy-saving devices Components used: LDR (Light Dependent Resistor) Transistor (2N2222) Resistors LED Power supply (Battery) This project is perfect for learning basic electronics and understanding how automatic lighting systems work.
