ABSTRACT: This paper is about the development of GSMbasedWirelessNoticeboard using Altera NIOS II soft- core processor system. In today's world the transfer of information is seen that important notices takes time to be displayed on the notice boards as the person has to go physically to display the desired message on the Noticeboard. We have designed an embedded soft-core based system to solve this problem. Here embedded system on peripheral chip (SOPC) reconfigurable system receives SMS’s from several authenticated mobile users and display’s the message on the NoticeBoard. The implementation of the interface with GSM Modem and Liquid Crystal Display (LCD) was carried out using NIOS II soft-core system running on Altera FPGA DE2 board having target as Cyclone II EP2C35F672C6. The designed NIOS II processor basedwirelessnoticeboard has various applications in several domains including public advertisements and educational sectors i.e in schools and colleges to update and display messages in real time from any geographical location of the user which reduces manual operation.
Wireless technology has a tremendous progress over the past few years. The ever-increasing use of wireless networks serves as an indicator of the progress in the area of wireless networks. As a means of communication, noticeboard are widely trendy with its applications ranging from schools, colleges, hospitals to major organizations. Notice boards effectively tackle the global problem of deforestation by conveying messages at large without the use of paper. The design of SMS driven automatic display Board which can replace the currently used programmable electronic display and conventional noticeboard. It is proposed to design receive cum display toolkit which can be programmed and later be used from an authorized mobile phone. It consists of ardunio board, controller AT mega 328P, Blue tooth .mobile phone and LCD display board. LCD display board is used for testing the proposed model. The interfacing of a ardunio board with mobile phone is quite easy with help of the terminal pin, read/write pin .Hence we employ Atmel ATmega328p microcontroller. The complexity of coding of our proposed system is less as compared with PC, but once programmed the micro controller works at its best. The design procedure involves identifying the different components and assembling all of them and it makes proper communication. Then coding process has to be done, which has to take care of the difference between two successive communications.
ARM Microcontroller:The microcontroller used in the present study is the LPC2148. Deploying LPC2148 series for the designing of an embedded system for dedicated application is reported by various investigators.Fig.4 depicts the pin configuration of microcontroller LPC2148.The LPC2148 are based on a 16/32 bit ARM7TDMI-S CPU with real time emulation and embeddedtrace support, together with 128/512 kilobytes (KB) of embedded high speed flash memory. A 128 bitwide memory interface and unique accelerator architecture enable 32 bit code execution at maximumclock rate. For critical code size applications, the alternative 16 bit thumb mode reduces code by morethan 305 with minimal performance penalty with their compact 64 pin package, low powerconsumption, various 32 bit timers,4 channel 10 bit ADC,USB port, PWM channels and 46 GPIOlines with up to 9 external interrupt pins .Due to tiny size and low power
Besides that, with embedded system that has grown greatly in recent years, the gadgets are increasingly becoming intelligent and autonomous. Mobile phones, refrigerators, automobiles and others are some examples of devise with built in intelligence which function based on operating and environmental parameters. The intelligence of smart device lies in embedded system. An embedded system, in general, in co-operates hardware, operating systems, low-level software binding the operating system and peripheral devices, and communication software to enable the device to perform the pre-defined functions. An embedded system performs a single, well-defined task, is tightly constrained, is reactive and computes results in real time.
A GSM modem  is a wireless modem which works with a GSMwireless network. It behaves like a dial-up modem. The major difference between them is that a dial-up modem sends and receives data through a fixed telephone line whereas a wireless modem sends and receives data through medium of radio waves. Just like a GSM cell-mobile phone, a GSM modem needs a SIM card from a wireless carrier in order to operate. This is a compact and portable terminal that can satisfy various data communication needs over GSM. It can be connected to a computer with the help of a standard RS232C serial port. It offers features like SMS, Data Services, Fax Services and Web Browsing. Data File transfer and remote login is also supported by GSM Modems. This is perfect equipment for construction sites, dams, factory plants and resorts where wired connectivity is neither practicable nor available. Both Dial-up Modems and GSM modems support a common set of standard AT commands. GSM modem can be used just like a dial-up modem. In addition to the standard AT commands, GSM modems support an extended set of AT commands. These extended AT commands are defined in the GSM standards. Extended AT commands give you the following options:
Wireless communication is best communication compare to wired communication. By this a long process involved in order to put up the notices on the noticeboard in the institutions is reduced. Urgent notices displayed immediately and it can be highlighted. In early days, the speed of the Data is controlled only through Wired Communication. But it is possible to the Data transfer or Receiver of the data from the Wireless Communication. So this paper deals with advanced noticeboard and time will be displayed on the board. There is a long process involved in order to put up the notices on the noticeboard in the institutions. Urgent notices should be displayed immediately and it should be highlighted LED-based displays can be of two types: dot-matrix and segmental. The ZigBee module is used to receive and transmit the data. ZigBee device is often used in mesh network to transmit data over longer distances for wireless communication.

variety of institutions which we come across in a daily basis. In the present generation the advertisement notice boards are being managed manually. This process is difficult to involve in order to put a notices on the noticeboard. This waste a lot of things like paper printer ink, manpower and also brings the loss of time. In this paper we have proposed a system through wireless transmit notices on a noticeboard using Wi-Fi. Wi-Fi can pass information for about 100meter distance Wi-Fi data rate has 1 or 2 Mbps. It access numerous point and to support network interfaces. It also makes the system compatible with more than one wireless technology our project name is “Digital WirelessNoticeBoard”. In this wireless technology is used to transmit the notice on to the digital display. In this an authorized user sends the image of notice via personal computer using a client based server over the Wi-Fi network towards the raspberry pi. Raspberry pi receives the notice and stores it in its memory and then display the images according to the program. The notice can be modified and altered according to client needs.

Abstract - Internet of Things is one the trending technologies of our time. It is used to connect various devices in a network that is made available anywhere within the range of the network. It allows a person to access his resources on the go. In this paper we propose an Ambient Reflector for a Smart noticeboard system using the concept of Internet of Things. The system uses Raspberry pi- Single Board Computer (SBC), acting as the processor with Wi-Fi network connectivity. It comprises of wireless sensor nodes, camera modules and a display unit forming the additional requirements of the system. The proposed system uses Evolutionary Prototyping methodology. The prime feature of the system is to display updates seamlessly to the users. The system’s root user updates the notices that are to be displayed on the designed interface. The system enables the users to use voice recognition tool to interact with the noticeboard. It has the ability to monitor the surrounding, by availing the camera module embedded to the framework. It also has an additional ability to automate the locality with ministration of sensors. The system is coded using Python for Rpi environment. The key motive of this IoT based Ambient Reflector, is to unveil the notices promptly. The proposed system replaces printed notices which saves time, shrinks man power and assists in achieving a greener environment.
Figure3:TheRelaySwitch Board Relay
According to ,a relay is simply an electrically powered switch. Relays enable one circuit to switch a second circuit which is usually separated from the first. For example a low voltage battery circuit can use a relay to switch a 230VAC mains circuits. There is no electrical connection inside the relay between the two circuits; the link is magnetic and mechanical (which explains why the relay is described as an electromechanical device).In the choice of the relay, the coil resistances were taken into consideration, this is important because the circuit must be able to supply the current required by the relay coil. From Ohm’s law, the current through the coil is given by

Most of the NoticeBoard are based on GSMBased, massage based some are power line communication based. A NoticeBoard is a place where people can leave public messages, for example, to advertise things to buy or sell, announce events, or provide information. Notice boards are often made of a material such as cork to facilitate addition and removal of paper messages or it can be placed on digital devices such as computers, phones so people can leave and erase messages for other people to read and see. The main aim of this research work is to make information dissemination much easier in a paperless community as the world tends to graduate into that line of interaction.
