XBees are a very simple way to enable wireless communication. Using wireless communication will expand the possibilities of a project, and is practically a necessity for a robot.
Two types of XBee communication that will be discussed are Arduino-Arduino communication and Arduino-Computer communication.
XBees cannot both send and receive data at the same time. If caution it taken, data should not be lost due to this fact.
XBees are one form of wireless communication. They use radio frequency to communicate over long distances (from 100m to over 1500m.) They do have issues transmitting through walls and through obstacles, but that is common to many types of wireless communication.
There are two main types of XBees: Series 1 and Series 2 . Series 1 XBees do not say that they are Series 1 on them, but that is one way to determine that they are Series 1. Series 1 is generally easier to use and configure. It is also faster than Series 2. The advantage of the Series 2 XBees is that there is a lower current draw.
This tutorial will go through the configuration of Series 1 XBees.
