Hi Tildes,

I'm looking to introduce my children (aged 10 or so) to simple electronics (blinking lights, simple sensors, ...). I've played with Arduino in the past, but I see that there are now many competing options: Arduino, cheap rip-offs, RPi zero, adafruit, ESP32, ... It's easy to get lost!

Which do you recommend? Ideally, I'd like something cross-platform and open-source, easy to set up (ideally a kit with everything included), and of course not insanely expensive.

Edit: thanks everyone for the good advice! There are so many good options...

I know those are easy to find on children's education materials, but the keyword here is simple. Anything kiddie, requiring too many clicks or that takes 3 seconds is off the table.

I kinda need to brush up on my super basic reasoning. In part, because a grown man should know the time table by heart, and in part, because I wanna convince myself that I did not get brain damage after being hit by a car (there's really nothing indicating that, I'm just paranoid).

I'm looking for something simple that presents me with the multiplication table and or simple calculations to answer under a time frame. The requirement for iOS is that my computer is broken.

And it really can be super simple, even something I open from a mobile web browser or transfer to my Kindle.

Additionally: there is no need for if to be an app. A huge list of exercises (with answers) would be greatly helpful.

Thanks!
