Wire a circuit on a breadboard, write the C++, press Run. Mokxi simulates an Arduino Uno, ESP32, Raspberry Pi Pico or STM32 in real time, right in your browser, with nothing to install. Every board and part is free. Circuit Doctor spots wiring mistakes before you fry a real part, and teachers get free lessons, classes, login cards and automatic checks. When it works, send the same sketch to a real board.
