This NOR Gate Working Model Kit is an educational digital electronics project designed for Class 10, 11, and 12 students. It clearly demonstrates the working principle of a NOR Logic Gate using two input switches (X & Y) and a bright LED output indicator (Z). Students can easily test different input combinations and understand Boolean logic with the help of the printed truth table and logic gate symbol on the board. Perfect for physics investigatory projects, computer science practicals, STEM learning kits, and school science exhibitions, this ready-to-use working model helps students grasp basic concepts of logic gates, digital circuits, and binary operations in a practical way. The compact, durable, and safe design makes it ideal for classroom demonstrations and board exam practical submissions. It operates with a simple battery connection, ensuring smooth and reliable performance. An excellent hands-on science project kit for learning digital logic gates in a simple, interactive, and engaging way.
