Actually, this $150 toy for kids is also a cool way for adults to mess around and learn how to assemble circuits and write computer programs.
The microcontroller contains a computer processor, storage for memory, timers and ports. The kit comes with 100 programs and a book of directions on how to put them into action. Some examples: a light meter that records data and a temperature sensor that tracks changes.
