Discover Electronics Kit, $49.99
I can’t say enough about the Discover Electronics Kit from Sparkle Labs. It’s playful and fun yet teaches you all the concepts you need to read schematics and build circuits. The projects start out by assuming you don’t know anything about electronics and build from there. A comprehensive video series walks you through every experiment. I really like that the kit doesn’t sugar coat the experience and uses uses real components that can be reused in other projects.
