Wireless electronics notice board

When a mobile user sends an information from his mobile, it is received by a SIM slot, which is integrated into a GSM modem at the receiver end.

This notice board displays the information on LCD display whatever you sent from the mobile. The message or data is read by the microcontroller pic18F through the maxwhich is only used for serial communication, means for transmission or reception the data.

But changing different notice day by day is a difficult process and consumes more time. Shopping Malls: The wireless electronics notice board is also used in shopping malls for display information about the shopping things rates and location of things wirelessly.

The programming language C have been used in this specific design. Railways Stations: The wireless electronics notice board is also used at railway station for displaying the information about railway timing or displaying any notice about government policy and railway headquarter.

Furthermore, designing of this wireless notice board project can be enhanced by providing a message storage facility by EEPROM non volatile memory. The block diagram of the wireless board mainly includes hardware and software components.

In this project, microcontroller, IC level shifter, GSM module are the most essential components.

Software requirements are Keil compiler and Embedded C language or assembly language. This notice board displays the information on LCD display whatever you sent from the mobile. In a GSM system, there are different types of cell sizes such as micro, macro, umbrella and Pico cells. You simply need to connect Gsm module Rx pin with tx pin of microcontroller and vice versa. A GSM device reduces the data and digitizes, then sends it down through a channel with two different streams of consumer data, which has a specific time slot. This modem works like a dialup modem and sim is required for communication. In this project, microcontroller, IC level shifter, GSM module are the most essential components. In microcontroller for setting the baud rate bps we set the timer 1 at FF0. It is mostly used in embedded system for serial communication. The major drawback of designing these boards is; not flexible and cannot be located anywhere due to messy wire. Working of Wireless Electronic Notice Board using gsm module The wireless electronic notice board consists of several components which have discussed deeply in above section and here we would be talk about the working of this wireless electronics notice board. Published on 25 Aug This article gives you an overview of how to design a wireless electronic notice board using GSM technology. The LCD is interfaced with the pic18F for displaying the message or data, which is sends by user from mobile phone from remote areas.

A GSM device reduces the data and digitizes, then sends it down through a channel with two different streams of consumer data, which has a specific time slot.

In a GSM system, there are different types of cell sizes such as micro, macro, umbrella and Pico cells. Now we will see how GSM modem interfacing with microcontroller.

Pic Microcontroller 18FF is very popular and 8-bit microcontroller belongs to pic a family. It is mostly used in embedded system for serial communication. Now you can observe the same message on the LCD display. This project is also used in organizations, schools and colleges. Furthermore, that displays it on a wireless notice board which is inbuilt with an LCD display. In dialup modem the data is send or received through the fix telephonic line but in GSM modem data is send or received though the radio waves. In microcontroller for setting the baud rate bps we set the timer 1 at FF0. Through the project you are going to build a unique system where you can give provide information on the Electronic Notice Board in Wireless manner where that notice board are controlled by an SMS using GSM modem. Here is a question for you, what is the main function of IC level shifter? Check out this video.

The problem is occurred when we communicate between TTL logic and CMOS logic because, here in wireless electronic notice board we are communicating between GSM modem and microcontroller therefore the problem would be occurred.
