           Since I have already introduced the easy to use and basic wireless rf modules I thought it would be a good idea to move forward and bring Xbee RF modules out into the open. These RF modules introduced a new standard into the DIY wireless world because of their superior performance and functionality.
           The Xbee modules work at the 2.4 GHz frequency which means smaller board and antenna size. Xbee modules have the ability to transmit Digital, PWM, Analog or Serial RS232 signals wirelessly.

The Xbee Wireless Module

Purpose & Overview of this tutorial
           The primary goal of this tutorials is to make a xbee wireless interface between two PIC microcontrollers. One PIC will act as a receiver, one PIC will act as a transmitter. The transmitter will have two buttons attached to it to give input. Depending on which button is pressed the receiving PIC will turn it's corresponding LED on. If no buttons are pressed the LEDs will remain off.
           In order to build the circuit and firmware necessary for this tutorial we'll have to get a better understanding of the Xbee modules and how they work. We'll take a closer look at them in the theory section. The firmware will be straight forward digital I/O and therefore shouldn't be very long. So without further adue let's get started.
