About

Wokwi is an online Electronics simulator. You can use it to simulate Arduino, ESP32, and many other popular boards, parts and sensors.

The advantages of using Wokwi include:

Immediate start: No need to wait for components or download large software. Everything required is available in your browser, enabling you to begin coding your IoT project within seconds.
Safe experimentation: Virtual hardware cannot be damaged, allowing users to experiment freely without the risk of destroying components. Mistakes can be easily undone.
Easy collaboration: Sharing a link to your Wokwi project facilitates obtaining help and feedback from others.
Code reliability: Helps in distinguishing between hardware and software issues, thereby increasing confidence in your code.
Unlimited resources: Access to an unlimited number of parts without concerns about cost or availability.
Supportive community: A maker-friendly environment where users can share projects, seek assistance, and find inspiration.

Unique features provided by Wokwi:

Wi-Fi simulation - Connect your simulated project to the internet. You can use MQTT, HTTP, NTP, and many other network protocols.
Virtual Logic Analyzer - Capture digital signals in your simulation (e.g. UART, I2C, SPI) and analyze them on your computer.
Advanced debugging with GDB - Powerful Arduino debugger for advanced users.
SD card simulation - Store and retrieve files and directories from your code. Paying users can also upload binary files (such as images)
Chips API - Create your own custom chips and parts, and share them with the community.
Visual Studio Code integration - Simulate your embedded projects directly from VS Code.
