Keil – C software Is used for programming for embedded project
The C programming language is a general-purpose programming language that provides code efficiency, elements of structured programming, and a rich set of operators.
The Cx51 Optimizing C Compiler is a complete implementation of the American National Standards Institute (ANSI) standard for the C language.
Since the Cx51 Compiler is a cross compiler, some aspects of the C programming language and standard libraries are altered or enhanced to address the peculiarities of an embedded target processor.

SOLDERMASK
ADVANTAGES
No separate wires are needed for communication purpose.
Easy to install.
Easy Data transfer One place to another.
Low power consumption.
DISADVANTAGES
Weather condition can affect transmission and Reception.
Component of the circuit are delicate so they need to handle carefully.
Data is lost when power is turned off.
Initial investment cost is more.
APPLICATIONS
It can be used for displaying public messages.
This type of communication can be widely very used in schools ,colleges, office ,house.
Business applications.
In hospitals.
Future Scope
Password System can be implemented.
We can use it for the display of symbols, signs and figures which can be easily understood.
Memory can be used to store data.
It can be used to cover a wider range by the use of Effective RF Transmitter and Receiver.
Conclusion:-
Form this article we conclude implementing
Wireless Notice Board that:-
It is user friendly i.e any layman can operate it.
Messages can be sent anytime & it can be corrected.
Messages lasts until the power in switched off.
