how do i communication set up communication on Xbee chips using a windows pc and an xbee explorer
Posting a bunch of related questions in different threads is not the way to do it.
Don't you know how to use google? There are a bazillion examples of using XBees to communicate between Arduinos.
The first thing that you have to do is to configure the XBees using X-CTU. In order to do that, you need to know what kind you have. Since you didn't tell us, you're on your own.
