Review Excerpt: LittleBits is a system of modular electronics that snap together with magnets. Each block, or module, has a unique function. There are several types of switches, LED lights, a light sensor, a motor and a tiny vibrating motor and more. Each part is color coded, to make it easy to quickly associate functions with colors. The result is that it is incredibly easy to “accidentally succeed” with the kits. If something doesn’t fit, it simply doesn’t work. The downside is that there’s a much narrower range of possible outcomes, given the price.
