1.1WIRELESS ELECTRONIC NOTICE BOARD USING R.F:-
Data Security is primary concern for every communication system. There are many ways to provide security data that is being communicated. However, what if the security is assured irrespective of the hackers are from the noise. This Project describes a design of effective security for data communication by designing standard algorithm for encryption and decryption. R.F. is a PAN technology based on the IEEE 802.15.4 standard. Unlike Bluetooth or wireless USB devices, R ....etc

Microcontroller Based Electronic Message Board



Abstract

The LED electronic message board is one of the fastest media to make people up to date. Message can be send through serially via keyboard or send by IR transmitter. It can perform multiple tasks like it displayed flash news up to 700 characters. It has also the ability to show time and date and at the same time it senses the temperature after every second and displays it on LED patches. It has many advantages like image cannot become fuzzy through lo ....etc

Abstract— This is the model for displaying notices in colleges on electronic notice board by sending messages in form of SMS through mobile; it is a wireless transmission system which has very less errors and maintenance. The hardware board contains microcontroller AT89c52 at the heart of the system. The microcontroller is interfaced with GSM Modem via MAX232 level convertor. It is used to convert RS232 voltage levels to TTL voltage levels and vice versa. The hardware also has a 64K EEPROM chip AT24C64. This EEPROM ....etc
