This interactive simulation shows a simple DC electrical circuit with a battery, resistor, LED, wires, and circuit board, along with animated yellow particles representing electron flow. A control panel adjusts voltage and resistance, toggles power, and switches between circuit and 3D views, with current and power readouts updating live. Built with Three.js and OrbitControls, the scene uses WebGL rendering with directional lighting, procedural geometry for components, and real-time animation driven by sliders.
