What can I say about this kit, other than that it offers projects galore, and is a genuinely great introduction to so many concepts. IF you're willing to put in the effort to learn! It's about as close to beginner friendly as something like this can get. There's no soldering necessary, all the parts are labelled and come in separate bags (for the most part), the instructions are understandable (if not super polished) and there's something for everyone to enjoy here. I will say, I think this kind of kit is best to go through with someone who has a bit more experience with electronics. Just giving it to an elementary age kid and letting them play with it alone is not the best idea. Of course, messing with electricity (even low voltage stuff like this) should be done with adult supervision, and I think it's just more fun for kids when they have help when they need it, but can otherwise experiment on their own terms. There are a lot of projects on the documentation website, and you can use Arduino/C code, MicroPython, or even visual programming in a Scratch-like environment called PictoBlox. I couldn't get PictoBlox working for me, but it should be easy to setup on Windows, macOS, Chrome OS, or Ubuntu, so I wouldn't worry. But I was able to work through several Arduino and MicroPython projects, and the setup instructions for both were pretty good. The one project I tried that didn't work (I didn't try them all, but I did attempt a wide range of them) was the live-streaming camera project. I ran into some code issues, and it didn't work for me. But I'd imagine if you reached out to Sunfounder about a technical issue like this, they'll help walk you through it if you provide enough details. And the code is open-source on GitHub, so any code fixes will be made available to everyone. And to their credit, some of these projects are really ambitious, and make use of the ESP32's unique capabilities. The provided projects can walk you through - from start to finish - things like making an Android app to control an RGB LED over Bluetooth, fetching live weather data from OpenWeatherMap, integrating your ESP32 into HomeAssistant, making a Telegram bot, and connecting an LED strip to the CheerLights network, to name a few. Very cool, very ambitious stuff that would have made me feel like a wizard as a kid. And that's not to mention the different games you can make with PictoBlox, that integrate hardware and game elements both ways. Like using a potentiometer as a controller for a breakout game, or controlling real-world motors and lights with in-game buttons. Again, wizard stuff that kids can be proud to accomplish. One thing to note, this project comes with an 18650 Lithium Ion battery. I was surprised that it came with the battery, since they are getting hard to find. There is an inherent danger in any kind of "naked" Lithium cell like this, I would just say to exercise caution. That being said, I know how difficult it is to find good portable power supplies for these types of projects which can output sufficient current. And they're trying to keep the cost reasonable, so I get it. On the topic of cost, I think it's really reasonable for everyone you get. Sure, buying these things in bulk would be cheaper, but it would be a serious challenge to try to source all of these parts separately, for under $100 - especially with individual shipping. This is incredibly convenient compared to the alternative of having to source these parts individually, and I think you get a wide range of components that are commonly used with these microcontrollers, which is really impressive. It's quantity and quality here, folks, and I don't think you can go wrong, here.
