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.
Everything Real Electronics Needs
Every feature is engineered to mirror real-world electronics — from atomic wire physics to intelligent fault detection.
Physics engine calculates voltage, current and resistance exactly as real electricity would. Ohm's Law enforced on every wire, every millisecond.
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.
Automatic detection of short circuits, overcurrent conditions, and broken loops. Error states are highlighted in real time with diagnostic overlays.
Zero install, zero plugins, zero Java. Opens instantly from any modern browser. Your circuits save locally — private and fast, always.
Fully responsive from 320px mobile screens to 4K desktops. The wiring canvas adapts layout, gesture controls and UI density per device.
Run multiple isolated circuit simulators on the same page simultaneously. Perfect for side-by-side comparisons, Academy modules, and embedded demos.
From Zero to Live Circuit
Three steps from opening your browser to watching real electrons flow through your design.
Click Launch Simulator — no login, no download, no plugin. The canvas is ready in under one second on any modern browser.
Pick resistors, LEDs, capacitors or logic gates from the palette. Drag them to the canvas and draw wires between their terminals.
Hit Run. The physics engine calculates instantly. Voltage labels appear on wires, LEDs glow, errors are flagged in real time.
