wokwi-features VS paddle-game

No, no - I have a half a dozen RPi's of varying revisions. Since they run Linux and the SDcards are less than robust, anytime you accidentially trip the power (which to me happens several times during hardware debugging sessions) you risk scrambling the rootfs and thus need to reflash a new SDcard. Some SDcards get damaged.

I recommend using Arduino and/or Wokwi (https://wokwi.com/) to get started.

More Wokwi Integration: Wokwi is an amazing embedded simulator and is great for getting started quickly. For a learner, there's no need for toolchain setup or even the purchase of hardware. There are many features as well that make it quite a flexible tool supporting a lot of features right from the browser. Users can also vote for more features. Still maybe at some point, one might want to tinker with physical hardware. However, at that point, they would have gained some confidence first. Currently, only ESP boards are supported with Rust on Wokwi. I hope for the variety to expand soon.

In addition to the other great suggestions here I wanted to point out that you can practice and learn a lot for free using an online simulator such as wokwi.com and tinkercad.com (among others)! And you don't have to buy an Arduino or any parts to get started!

And you can prototype all of this first to get it working for free using an online simulator at sites like wokwi.com or tinkercad.com!

If you don't have the budget for real hardware consider the simulator at https://wokwi.com/ It works with Rust (at least for ESP32, haven't tried other architectures). Bonus: you can't blow up the electronics by a wiring mistake.

I spent a bit of time today with a few FastLED programs and uploaded them to wokwi.com on a simulated Arduino Nano and a WS2812 strip of 64 LED's (not in a 2D matrix). The chatgpt requests I made were:

https://wokwi.com/ is great for simple, digital only stuff.

https://fritzing.org/ will kind of lay out the PCB for you, but it's kind of a pain in the ass.

Wokwi and Fritzing are more "Breadboard Simulators" than real circuit simulators, but they do have their place.

Another cool thing you may want to try is making a simulator https://wokwi.com/

Web Serial API would also mean one could create an Atari-style paddle controller to go with this game, kind of like this project: https://github.com/drohen/paddle-game

Once you get a bit of experience, have a go at building this: https://github.com/drohen/paddle-game it is something I put together in my spare time in a week, you might have fun replicating it.

I have a bunch of notes and the code is available on github. Feel free to ask any questions!

The repo is on github, and I've added a bunch of notes on how it all works. Feel free to get in touch if you have any questions.

I recently completed a one week personal challenge to build something interesting using just a potentiometer and button. I am learning more about the web serial api, and decided to connect these components to a pico, read the values and send it to a web app. I wanted to build something fun and music, so I created this elektroplankton-inspired game at the same time. The code is available, open source, along with the live app. I will update the documentation shortly. The code for the pico is also available, and can be adapted to an arduino or whatever. Considering how easy and fun this was, I'm hopeful that the web serial api is here to stay.

I think that this project could just as easily work with an arduino uno, and of course, the code could easily be adapted. I only have a few final things I need to do in the app before I feel like I can say this is completed and move on to writing a full reflection and possibly a guide on how I did this. The code for the app and the pico is available on github, I will update all the readme and code comments to make it easier to follow along. I'll post a video as well demonstrating it all working.

I created challenge for the Raspberry Pico subreddit to try and build something out of a potentiometer and button. And my idea is summarised in the title of this post. This is the code but as of this post it isn't presented super well, just wanted to finish the proof of concept before creating more structure. I'm using a bunch of nice little utility libraries, and ToneJS. The plan is to connect the app to my custom controller using the Web Serial API.
