A Small Idea ...
Project
Our objective is to make a portable device that will transparently control devices that are attached or running on the personal computer.
The Idea
Use radio transceiver to communicate between PC and handheld PC
The handheld PC will be able to manage certain external devices and internal software on the PC
Application
CD Player
Identification Card
Device Controller
CD Player
Be able to play the CD Player on the PC from the handheld PC
Identification Card
Be able to: store information on the card
retrieve and update information on the card from the handheld PC
download the information from the handheld PC to the database on the PC
Device Controller
Simulate applications that can be connected to the serial or parallel ports on the PC
Test the simulation by connecting a LED to the different ports and controlling the LED by the handheld PC

Connection of all equipmentBuild a simulated application that
connects a LED to the different ports
Team Member Responsibilities
Chris Connection of LED to different ports Make applications that light up the LED Radio Frequency Communication
(sending and receiving data) Application on the handheld PC that
sends appropriate data
Vanessa Device Controller for the PC that reads
data from the serial port and sends that data to the right application
Radio Frequency Communication - application that sends and reads the right data through the radio
Kaori Revision of CD Player Code Programming Smart Card Application that interprets the
information sent by the reader Application on the PC that interprets
data from the handheld PC
