ElectroLab focuses on understanding — how circuits work, what each component does, and why current flows the way it does.
For actually building and experimenting with circuits, these dedicated simulators are far better tools. They are free, browser-based, and purpose-built for hands-on practice.
Recommended workflow
Learn the concept here in ElectroLab → then build and experiment in Wokwi or Tinkercad. Theory + practice together is the fastest way to actually understand electronics.
Best for Arduino & ESP32 projects
Simulate real microcontroller code alongside components. Write code, wire circuits, and see your program run — no hardware needed. Supports Arduino, ESP32, and Raspberry Pi Pico.
Best for visual drag-and-drop beginners
Autodesk's free in-browser circuit simulator. Drag components, wire them up, hit Simulate — breadboards, sensors, LEDs, motors all included. Great starting point before real hardware.
Best for understanding analog circuits
Real-time analog simulation with live voltage and current visualizations. Perfect for understanding how resistors, capacitors, op-amps, and filters actually behave.
