A fully local, open-source Arduino emulator. Write Arduino code, compile it, and simulate it with real AVR8 CPU emulation and 48+ interactive electronic components,All running in your browser. GitHub: https://github.com/davidmonterocrespo24/velxio
The goal of this project was to learn more about how emulators work internally: CPU instructions, memory management, and low-level architecture.
It's still experimental, but it already runs basic instructions and I'm continuing to improve it.
I built Velxio to explore how microcontroller emulators work internally.
It's an Arduino environment that runs entirely in the browser. You can write sketches, compile them with arduino-cli, and simulate circuits using a real AVR8 CPU emulator.
Features:
- Arduino Uno / Nano support
- Raspberry Pi Pico (RP2040)
- GPIO, SPI, I2C, UART, ADC peripherals
- interactive electronic components
The goal is to create an open-source environment for experimenting with embedded systems without installing anything.
I built a small emulator project called Velxio.

What parts have you exactly built?
All I see are dependencies that are glued together with claude.
Can you clearify exactly what you have developed?

I'd love feedback from embedded developers!
Thanks for the share, it looks great! Can I load my own OS in rpi?
Did you see that it's an rpi pico, which doesn't really run OSes in the traditional sense?
You are right, when I skimmed through I thought it’s an sbc one. Still very cool, would try it later.

[Edit] Which also does Arduino.
Very cool. I can't wait to play around with this!
This is amazing!
