It allows you to write Arduino sketches, compile them using arduino-cli, and simulate circuits with a real AVR8 CPU emulator and interactive electronic components. The platform supports multiple boards including Arduino Uno, Nano, Mega, and Raspberry Pi Pico, with peripherals such as GPIO, SPI, I2C, UART, and ADC mapped to visual components. The goal of the project is to create an open-source environment where developers and makers can experiment with Arduino circuits

Hi everyone!
I built Velxio as a way to explore how microcontroller emulators work internally.
The idea was to make an open-source Arduino environment that runs entirely in the browser, where you can write code, compile it, and simulate circuits without installing anything.
It currently supports AVR8-based boards like Arduino Uno and Nano, as well as Raspberry Pi Pico through RP2040 emulation.
I'd love to hear feedback from developers, embedded engineers, and makers.

This is very awesome project🙌🏻 I hope there would be "near to realistic" simulation of voltage and current, and there would be warning for possible components damage if there are issues in the circuitry. This would help not just beginners but also other devs who want to simulate/visualize their own projects.

@software_escarlata Thank you! That’s definitely something we’d love to explore. Our goal is to move toward more realistic simulations over time. Really appreciate the feedback!
