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!
