Project Name: 3in1 communicater
Author/Designer: Chew Poh Seng
Project Description: Communication between two LCD using either Xbee, APC220 or RF433Mhz
Photo/Picture/Figure/Diagram/Flowchart:

This project is to communicate between two LCD (numbers and text) using
either XBEE, APC220 or RF 433Mhz. Each got their strong and weak characteristic.

For instance, baud rate of XBEE was great but high power consumption.
APC220 communication can reach up to one KM or more but the module was quite expensive.
RF433Mhz was cheap but not really suitable for text communication,
the speed is slow and character will drop while communicating.

The * key was use to make error correction.
The 0 key was use to clear the whole LCD.
The # key was use to send the text.

This is a good learning project for various type of wireless communications. Is it possible that you share the schematic and code? If you want to keep those to yourself, perhaps a simplified connection diagram and how you interface with these three modules will do Same comment goes to your other projects...
