We've been working on this one for a long time. Its designed to be a fun, non school like introduction to Arduino and microcontroller programming.
It contains an Arduino a breadboard and a load of fun components (LEDS, a motor, a servo, a breadboard, jumper wires, temperature sensor, light sensor and more). Along with a printed guide and breadboard layout sheets (pin them to a breadboard and they'll show you where each component goes).
Check out all the details on the Instructable:
We also produce a kit with all the components bundled, as well as guide and breadboard sheets printed.
