need help!!!!!!

hi..
i am doing a project on zigbee.I am trying to control the room lighting using sensors n Zigbee.
At the transmitter a zigbee is connected to a PIC microcontroller n at the receiver another zigbee is connected to a pic microcontroller.a sensor also needs to be connected to the microcontroller.
could anyone help me with the circuit.
waiting for u r reply..

try using PIC16F873 uC. The zigbee module operates on USART interface. The Tx line of the PIC uC can be given as input to the zigbee module.
 

Which Zigbee you are using?
I have used "ember zigbee from CCS" and it has SPI interface.
what kind of interface u have in your zigbee?
 

For an idea you can visit the following website

**broken link removed**

If you will run your microcontroller at 5v then you require 5 to 3.3v conversion at the Tx pin of microcontroller.
You can also operate you pic microcontroller at 3.3v then you dont need any voltage conversion.
