While it’s easy to see the Arduino and the Raspberry Pi as competitors – they’re both low-cost electronic devices aimed at the hobbyist market, after all – in truth they’re extremely complementary: the Arduino excels at real-time control and sensing, while the Pi provides cheap network connectivity and powerful data processing capabilities.
That’s clearly been the thinking of Ciseco in designing the Raspberry Pi Wireless Inventors Kit, or RasWIK: a bundle of components and accessories, it’s designed to make working with the Arduino on the Raspberry Pi as simple as possible and showing users just what potential is opened up when the two are connected over a radio link.
