Recently, I accidentally discovered a great online simulation tool (Wokwi) that supports multiple platforms and mainstream development boards on the market, such as: STM32, ESP32, Arduino, Raspberry Pi, etc.

It also supports common sensors and display devices (LCD, LED screens), and can play music, connect to the internet, and use logic analyzers. The key point is that it provides many practical project cases.

Here’s a video (case) for everyone:

The highlight of this tool is: Free! Everyone can use it with confidence.

From the webpage, you can see that the Wokwi online simulation tool supports several mainstream platforms, such as STM32, ESP32, Arduino, Raspberry Pi, etc.

Then, each module has many project cases. For example, the Arduino module includes many projects as shown below:

Featured Functions

• wifi Simulation: Connect your simulated projects to the internet. You can use MQTT, HTTP, NTP, and many other network protocols.

• Virtual Logic Analyzer: Capture digital signals in your simulation (such as UART, I2C, SPI) and analyze them on your computer.

• Advanced Debugging with GDB: A powerful debugger for advanced users of Arduino and Raspberry Pi Pico.

• SD Card Simulation: Store and retrieve files and directories from your code. Club members can also upload binary files (like images).

• Chip API: Create your custom chips and components and share them with the community.

• Visual Studio Code Integration: Simulate your embedded projects directly from VS Code.

For more information about the Wokwi online simulation tool, you can refer to the official documentation:

How to Use Wokwi Online Simulation Tool

The usage of the Wokwi online simulation tool is very simple, as long as you are not a fool (I believe anyone reading this article is not a fool), you will basically get it at a glance.

Select the corresponding platform from the homepage, choose a sub-project, and then you can edit the project. After editing, just click to run the simulation.

Of course, in addition to editing software, the hardware can also be edited. For example: here is an added connection wire for a pin:

Isn’t it simple? When you have time, you can try it yourself; there are many interesting and fun projects inside.

For example: let me show you another project about the servo:
