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
