🔔 Burglar Alarm with Transistor, LDR, and Buzzer In this project, learn how to build a simple burglar alarm that activates when light conditions change, such as opening a box. This beginner-friendly circuit uses a transistor, an LDR (Light Dependent Resistor), and a buzzer to detect changes in light and trigger an alert. Circuit Diagram: https://drive.google.com/file/d/1GaR1u9NnbEuPEdeqzc9-WShtLscbPJWu/view?usp=sharing What You’ll Learn: How an LDR works to sense light variations Using a transistor as a switch in electronic circuits Creating a basic security alarm system Components Used: LDR (Light Dependent Resistor) Transistor (e.g., BC547 or similar) Buzzer Resistors Breadboard and jumper wires Watch as we guide you step-by-step through the circuit setup and demonstrate how the alarm responds to changes in light. This is a practical and fun project for beginners and electronics enthusiasts! 👉 Don’t forget to like, share, and subscribe for more exciting electronics projects and tutorials! #BurglarAlarm #LDRProject #DIYElectronics #ElectronicsForBeginners
