STANNUM, an ESP32 simulator with a circuit to wire
A browser-based simulator lets beginners write Arduino code, assemble a virtual circuit, and run it on an emulated microcontroller.
Field notes
The simulator models a complete beginner workflow rather than merely animating a circuit: users write Arduino code, connect virtual modules pin by pin, compile it, and inspect outputs through LEDs, displays, buzzers, and a serial monitor. The page lists 28 modules, including the BME280, NEO-6M GPS, SSD1306 OLED, and HC-SR04 ultrasonic sensor, across three ESP32 board layouts. It states that physical-board compiler compatibility is part of the design.
