A Few advanced features of Wokwi Arduino Simulator

Load the HEX file and start executing your project!

You can effectively run existing Arduino sketches as well on the Wokwi Arduino simulator. To do this, you can go to the command palette (shortcut key F1 )

Here is the screenshot:

Loading hex files and running Arduino program on the Wokwi Arduino Simulator

You can find the option in the drop-down menu. You can also notice a lot of other state of the art options. This makes the Wokwi Arduino simulator, the one with a modern useful and efficient Arduino editor among the available online Arduino simulators.

You can also download the file for your reference on Wokwi Arduino Simulator

You can download the compiled hex file as well. The below screenshot has that option as the second element in the list.

You can view the code in assembly language as well

Having a look at the assembly code as well is a dream come true for certain debug use cases. You can see where your code is getting stuck or losing the normal control flow.

For example, during debugging, one of the examples was always running the setup() function back to back. In real hardware, debugging this would be impossible. On the Wokwi Arduino simulator, it was very easy to find out what is happening and later fix the bug in the code. You can refer to the questions and the solution posted (using the Wokwi Arduino simulator).

FastLED platform to unleash your creativity

You can use the Wokwi Arduino Simulator to engage with your creative skills. Here is one example of a FastLED matrix. This example simulates a working fighter software. Think about the efforts and time needed to set up the same with the real hardware, before you can start testing your code!!!

Amount of effort needed to create a matrix like this. In case if you need to change the matrix size by 10 LEDs, the effort will be double the original. it will take more than a month to get one simple FastLED matrix to design, fabricate, assemble and test. It takes about 10 minutes to create a similar project on the Arduino simulator. You can focus on implementation and testing rather than rigging up and other logistics. The link to the below project is here.

It doesn't mean that you should never go to hardware. Arduino simulators help you to get your plan on paper. You can easily verify how it is going to look, test your code up to an extent and then confidently go ahead with the hardware implementation. Here is the article on the story of an idea getting its wings in the Arduino simulator, later, produced and it works instantly!

On the other hand, sharing projects were never simple. You are able to read about the fighter FastLED project or even the Splendida project because of the Arduino simulator. It is easy to share hardware among others but the simulation projects can be shared in just a click! Hence, You will always find the Wokwi Arduino simulator, a favourite tool for FastLED projects especially.

Easy project sharing

Talking about the sharing feature of the projects, the Wokwi Arduino simulator has made it really easy. It is just a click, literally. Your friend can open the project, and just run it out of the box. Here is a snapshot from the Arduino simulator where you can simply click on the share button to copy the link. You can share the link which can be opened by anybody worldwide and start executing the project on the go.

I would like to give a link here where earlier features are compared here.

You can easily add more libraries int your project on the Wokwi Arduino simulator

To include a library, go to the code editor and type # on an empty line. You'll see a autocomplete dropdown with #include suggestions for popular libraries.

By default, Wokwi compiles your code with the standard built-in Arduino libraries, such as Wire.h and SPI.h.

To add third-party libraries to your project, add a "libraries.txt" file to your project. List the libraries that you want to include, one library per line. Lines that start with "#" are comments.

For example, the following file will install the latest versions of Servo and FastLED, as well as version 2.3.0 of MySensors:

You can find the library names in the Arduino Library Manager. Alternatively, you can find it inside the source code of the library. Look for the name field of the library.properties file.

At the moment, only libraries from the Arduino Library Manager are supported. If you need a library that is not available on the Arduino Library Manager, you can either copy the library source files to your project or submit it to the Arduino Library Manager.

Planned next action: additional features in version 2 soon!

Thank you for your time.
