It’s not quite as complex and full-featured as Wokwi, as you can’t build your own circuits, but you still have an area to write your code and save it locally, icons for digital pins (red = low, green = high) and analog pins (value from 0 to 255), and a serial monitor with a field that allows you to send commands as needed. To test a program simply click on the run button at the top.
Leonardo told CNX Software the project is a work in progress and can be useful for regions or countries where it may still be difficult to purchase components. You’ll just need a web browser without or without Internet access and you’re good to go. The Arduino simulator will also automatically detect the default language and switch to English, Spanish, Italian, French, or Portuguese. Other languages should be pretty easy to add with only a few strings to translate.
Jean-Luc started CNX Software in 2010 as a part-time endeavor, before quitting his job as a software engineering manager, and starting to write daily news, and reviews full time later in 2011.
