While I was busy working on the simulator itself (and some other stuff), I'm thrilled so see where other people have taken this open source library, and how they built useful applications and educational materials around it.
Here are some examples that I'm particularly excited about:
Dawson College Virtual Lab
Tawfiq Jawhar is building a beginner Arduino programming course for his students. He integrated VuePress with AVR8js and Wokwi Elements to create a learning environment with integrated exercises, where you can tinker with the code, run it in simulation and get immediate feedback.
AVR8js Electron Playground
This project, created by Anderson Costa from Brazil, aims to bring AVR8js simulation to the desktop. He collected various code examples and snippets and put everything together into a nice app that lets you tinker with many different pieces of hardware at once:
If you want to take it for a test drive, simply head to his GitHub repo, clone it, and run
npm install followed by
npm run dev. Then, play around with the built-in code examples by clicking one of the buttons on top (e.g.
fire ?), then "COMPILE" and "RUN".
Anderson also experimented with running 6502 simulator inside the Arduino simulator (inception style), which currently runs a EhBASIC interpreter, and should theoretically be able to run Atari 2600 games and other cool stuff. I'm really looking forward to seeing where Anderson will take it!
Soulmate LED Pattern Editor
Soulmate is the brand name of programmable smart LED matrices, designed by Elliott Kember. He created an online editor which allows you to play around with different LED patterns programmed with Arduino and the FastLED library:
Electronic Circuit Simulation with CircuitJS1
Mark Megarry combined AVR8js with CircuitJS1, an electronic circuit simulator that runs in the browser. You can probably see why combining an Arduino simulator with an electronic circuit simulator can be a good idea, and this is what the result looks like:
You can attach any Arduino pin to any point of the analog circuit, and it works like a charm. For instance, the above example will drive pin 13 high when pin 7 is high (thus, making the switch control the state of the LED):
Info1 Board Going Virtual ?
Speaking of collages, Glenn Feunteun, an embedded systems teacher at the French Université de Bretagne Occidentale, is working on creating a virtual version of their Info 1 board, which they use for their introductory course:
Glenn says, that since the COVID 2019 outbreak, the school has gone full remote and they are looking for ways to teach these concepts to students at home. This prompted the creation of the "Virtual Info-1", with pretty much the same hardware:
While working on this project, Glenn has contributed code to improve the simulation performance (here and here), helped with the AVR 16-bit timer implementation, and even created the Speaker wokwi-element.
And that's it!
When I started working on AVR8js, I wasn't sure whether releasing it as a MIT-licensed open source project was a good idea. One year later, I am so happy to see how talented engineers used this library in their projects, and I'm sure there's much more to come!
I'm now working on improving the Wokwi Arduino simulator, based on feedback from the FastLED community, and building a page where you can tinker with many popular Arduino libraries, as well as working on GoodArduinoCode.
If you build something cool with these technologies, please let me know. I'm waiting for your messages at firstname.lastname@example.org!
