Design, simulate & build real hardware.
In your browser.
Go from idea to working breadboard circuit with wiring diagrams, parts lists, and assembly guides. Test everything virtually before buying a single component.
Build with Real Electronic Components
Drag and drop realistic components — breadboards, Arduino, sensors, and more
From Idea to Working Hardware
Design, test, and build real circuits in 4 simple steps. No prior experience needed.
Design
Drag components onto the breadboard. Connect them visually with wires. Build your circuit in minutes.
Simulate
Test your circuit virtually with SPICE simulation. See waveforms, voltages, and current in real-time.
Export
Get your parts list with prices, wiring diagram with color-coded wires, and step-by-step assembly guide.
Build
Follow the assembly guide to build your circuit on a real breadboard. Upload code and power it on!

Everything to go from idea to real hardware
Design circuits visually, test them virtually, and get everything you need to build them physically.
Realistic 3D Breadboard
See your circuit in photorealistic 3D. Watch resistor color bands, glowing LEDs, and actual Arduino boards — exactly as they'll look when you build it.
Test Before You Build
Catch wiring mistakes, wrong resistor values, and power issues in simulation. Find errors before buying parts and save time and money.
Real Arduino Code
Write and test Arduino sketches with cycle-accurate ATmega328P emulation. If it works here, it works on your desk. No board required to start.
Parts List Generator
Get a complete shopping list with prices and supplier links. Know exactly what to buy and how much it costs before you start building.
Wiring Diagrams & Assembly
Export Fritzing-style wiring diagrams and step-by-step assembly instructions. Go from simulation to physical circuit with confidence.
Live Waveform Analysis
Watch voltage and current in real-time with built-in oscilloscope. Debug your circuits like a pro with live signal visualization.
