Wokwi

Overview of Wokwi

Wokwi is a comprehensive online simulator for Arduino, ESP32, STM32, Raspberry Pi Pico, and other popular microcontroller platforms. Designed for makers, educators, and electronics enthusiasts, it enables browser-based circuit design, simulation, and testing without physical hardware, making it ideal for learning Arduino programming, IoT prototyping, and experimenting with open-source libraries when hardware access is limited.

The platform is widely used in education, with universities like Harvard and NTNU using Wokwi Classroom for teaching electronics and embedded systems. Wokwi Pro offers advanced capabilities, including integrations with IDE tools like VS Code and JetBrains, and CI/CD workflows. Its collaboration with Tiny Tapeout allows users to transform simulated designs into actual silicon chips, bridging virtual prototyping and real-world Emulator applications.

How to Use Wokwi

To get started, visit the website, choose a microcontroller board such as Arduino Uno or ESP32, and build circuits using the drag-and-drop interface. Write code in the built-in editor, use library support for peripherals, and run simulations to observe real-time behavior of LEDs, sensors, and displays. For advanced workflows, install the Wokwi extension in VS Code or set up Wokwi for CI automation. Projects can be saved, shared, or submitted for physical fabrication via Tiny Tapeout.
