Live Circuit Simulation Platform Build. Wire. Understand. A browser-native electronics lab where circuits come alive. Drag components, connect wires, and watch real electricity flow — no installation, no textbooks, just hands-on learning. Launch Simulator Explore Academy No Install Works on Mobile Free to Start circuit_01_basic_led.cf RUNNING 9V 220Ω LED 4.5V 2.1V 10µF 1kΩ LED ● DETECTOR Short: NONE Voltage: OK Current: 18mA Simulation Running — Real-time Physics Active Nodes: 6 FPS: 60 Load: 12ms 60fps Realtime Engine 0ms Install Time 50+ Components ∞ Circuits Per Page Core Highlights Everything Real Electronics Needs Every feature is engineered to mirror real-world electronics — from atomic wire physics to intelligent fault detection. Real-Time Circuit Simulation Physics engine calculates voltage, current and resistance exactly as real electricity would. Ohm's Law enforced on every wire, every millisecond. LIVE ENGINE Drag & Drop Wiring Tap or click components from the palette, drag to position, and draw wires between nodes. Intuitive on desktop and touch-first on mobile and tablet. TOUCH READY Smart Fault Detection Automatic detection of short circuits, overcurrent conditions, and broken loops. Error states are highlighted in real time with diagnostic overlays. AUTO DETECT 100% Browser Native Zero install, zero plugins, zero Java. Opens instantly from any modern browser. Your circuits save locally — private and fast, always. NO SERVER Multi-Device Support Fully responsive from 320px mobile screens to 4K desktops. The wiring canvas adapts layout, gesture controls and UI density per device. ADAPTIVE Sandbox Architecture Run multiple isolated circuit simulators on the same page simultaneously. Perfect for side-by-side comparisons, Academy modules, and embedded demos. MODULAR No Install Required WiringLab runs entirely in your browser via WebAssembly and the Canvas API. No downloads, no plugins, no account required to start simulating. Getting Started From Zero to Live Circuit Three steps from opening your browser to watching real electrons flow through your design. 01 Open the Simulator Click Launch Simulator — no login, no download, no plugin. The canvas is ready in under one second on any modern browser. 02 Drag & Wire Components Pick resistors, LEDs, capacitors or logic gates from the palette. Drag them to the canvas and draw wires between their terminals. 03 Simulate & Learn Hit Run. The physics engine calculates instantly. Voltage labels appear on wires, LEDs glow, errors are flagged in real time. Ideal For Who Uses WiringLab?
