    I built a small emulator project called Velxio.

    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.

      Hi HN!

      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'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.

    Very cool. I can't wait to play around with this!
