Can you explain in more detail how well it works with Arduino? Could I take 3 arduino components and 3 spark components and have them integrate to do something useful?
No. The spark dev kit includes an STM32F microcontroller. You can think of this as kinda like your Arduino. You can write programs for it, but you'd have to use their online IDE I think since Arduino native doesn't support STM32F.
It is basically an Arduino dev kit w/ the WiFi module integrated. If you want to use an existing Arduino shield you'd have to buy their Shield Shield which you can plug your spark core into and then plug in the other Arduino shield.
