Question 1

Is Virtual Breadboard Lab free to use?

Accepted Answer

Yes, Virtual Breadboard Lab is completely free. There are no subscriptions, ads, or hidden costs. It runs entirely in your browser without requiring account registration.

Question 2

What components can I simulate?

Accepted Answer

VBL supports batteries (9V), LEDs (red, green, blue, yellow), resistors (220Ω to 10kΩ), switches, buzzers, transistors (NPN/PNP), logic gates (AND, OR, NOT, NAND, NOR, XOR), and 555 Timer ICs. All components follow real-world logic behavior.

Question 3

How does Virtual Breadboard Lab differ from physical breadboards?

Accepted Answer

VBL is a logic simulator, not a physics engine. It instantly evaluates circuit behavior using graph theory algorithms. You cannot damage components, short circuits are safely detected, and there are no voltage drops or component heating.

Question 4

Can I save my circuits?

Accepted Answer

Yes, VBL includes undo/redo functionality and local browser storage. Your circuits persist across sessions. Export/import features may be added in future updates.

Question 5

Does Virtual Breadboard Lab work on mobile devices?

Accepted Answer

VBL is optimized for desktop browsers with mouse/trackpad interaction. Mobile support is experimental. For best experience, use a laptop or desktop with Chrome, Firefox, Safari, or Edge.

Question 6

Apakah Virtual Breadboard Lab gratis? (Bahasa Indonesia)

Accepted Answer

Ya, Virtual Breadboard Lab sepenuhnya gratis. Tidak ada iklan, biaya berlangganan, atau biaya tersembunyi. Aplikasi berjalan langsung di browser Anda tanpa perlu mendaftar akun.
