I want to connect an Arduino/Ethernet Shield to a network, and send it simple commands wirelessly. The Arduino should get/parse the commands and do something on then network accordingly. These are simple commands. Like 5 buttons on/off.
If I use Xbee, do I need an Arduino at both ends? Or does the Xbee itself have some digital pins on it I can use for input? I want my remote to be small.
I could also use IR, but line of site is a hassle. How about blue toothe? What else is there?
