Hi,
I've recently jumped head first into the world of Arduino. I'm looking for some advice. I have 2 Arduino Unos and I would like to make them communicate with each other. Something simple like sending an int from one Uno to the other add 1 to that value and send it back. Maybe make the Unos flash an LED to indicate the current value of the int being passed back and forth. To do this I bout 2 Xbee Series 1 modules, but I didn't but any shields for them. I've looked around the net for possible shields and I've seen small ones, large ones, and ones that connect to USB. I'm looking for which shield to buy and from which vendor.
Thanks in advance
