Notice Board Using RF
[attachment=23191]
ABSTRACT
In Today’s Electronic communication take important role. Today’s Communication technology the chatting system from one Place to another is easy and fast. The main aim of this project is to display the notice using PC with RF Communication. The purpose of the project is to send data from pc and display on LCD by using RF.
In our project we have two sections, one is transmitter section and another one is Receiver section. The two sections are designed around a microcontroller as a control unit with all the devices interfaced to it. The main aim of the project is to transmit the data using wireless communication. At the receiver side, it will display on LCD which works like a notice board using RF.
DESCRIPTION:
The hardware used in the transmitter section are microcontroller, RF transmitter, encoder, serial driver, power supply .In the receiver section microcontroller, RF receiver, decoder, LCD, power supply .The software used for this project are keil, embedded ‘C’, express PCB, express schematic.
INTRODUCTION
OVERVIEW
Notice Board is primary thing in any institution / organization or public utility places like bus stations, railway stations and parks. But sticking various notices day-to-day is a difficult process. A separate person is required to take care of this notices display. This project deals about an advanced hi-tech wireless notice board
Electronic notice board is a common device that is used to display information. The information or messages are displayed using dot matrix. The wireless system for dot matrix display is a method using Radio Frequency as transmission medium. The system consists of two modules: transmitter and receiver. The transmitter module is used by a user to place a message through an input module PC. The information then transmitted using RF technology to the receiver. It then will be decoded and displayed on electronic notice board.
WIRELESS HISTORY:-
The wireless era was started by two European scientists,James Clerk Maxwell and Heinrich Rudolf Hertz. In 1984, Maxwell presented the Maxwell’s equations by combining the works of Lorentz, Faraday, Ampere and Gauss. He predicted the propagation of electromagnet waves in free space at the speed of light. His theory was accepted 20 years later, after Hertz validated electromagnetic wave (wireless) propagation. Hertz demonstrated RF generation, propagation and reception in the laboratory. His work then continues by Guglielmo Marconi after 2 decades. He then acquires a method for transmitting and receiving information. Marconi started to commercialize the use of electromagnet wave propagation for wireless telegraphs and allowed the transfer of information from one continent to another without physical connection. Since the cellular mobile phone system was introduced in the early 1980’s, the wireless industry has gone several generations of revolutionary changes. Other examples for this application are in remote sensing, broadcast, smart automobile and highways and so on.
2.2 NOTICE BOARD HISTORY:-
We are instrumental in providing a wide variety of display notice boards that can be used to display anything, be it some painting, any article, a notice or any other information. Offered at competitive prices, these are available in various sizes and shapes and are extremely durable.
Embedded C
*Keil software for c programming
ABOUT KEIL SOFTWARE:
It is possible to create the source files in a text editor such as Notepad, run the Compiler on each C source file, specifying a list of controls, run the Assembler on each Assembler source file, specifying another list of controls, run either the Library Manager or Linker (again specifying a list of controls) and finally running the Object-HEX Converter to convert the Linker output file to an Intel Hex File. Once that has been completed the Hex File can be downloaded to the target hardware and debugged. Alternatively KEIL can be used to create source files; automatically compile, link and covert using options set with an easy to use user interface and finally simulate or perform debugging on the hardware with access to C variables and memory. Unless you have to use the tolls on the command line, the choice is clear. KEIL Greatly simplifies the process of creating and testing an embedded application.
Simulator/Debugger:
The simulator/ debugger in KEIL can perform a very detailed simulation of a micro controller along with external signals. It is possible to view the precise execution time of a single assembly instruction, or a single line of C code, all the way up to the entire application, simply by entering the crystal frequency. A window can be opened for each peripheral on the device, showing the state of the peripheral. This enables quick trouble shooting of mis-configured peripherals. Breakpoints may be set on either assembly instructions or lines of C code, and execution may be stepped through one instruction or C line at a time. The contents of all the memory areas may be viewed along with ability to find specific variables. In addition the registers may be viewed allowing a detailed view of what the microcontroller is doing at any point in time.
Conclusion:
The project “NOTICE BOARD WITH USING RF” has been successfully designed and tested. Integrating features of all the hardware components used have developed it. Presence of every module has been reasoned out and placed carefully thus contributing to the best working of the unit. Secondly, using highly advanced IC’s and with the help of growing technology the project has been successfully implemented.
