PC -MC communication (AT89C2051 + Tx/Rx)

The advent of new high-speed technology and the growing computer capacity provided realistic opportunity for new home controls and realization of new methods of control theory.
This project describes a new economical solution of communication system. The presented home system can be used for different sophisticated applications. The distant temperature data can be monitored through PC with help of the microcontroller.
The intelligent control software, which has been developed using high level graphical programming language (Visual Basic). A complete solution of a communication system is presented in this project.
