Code 546 Message decoder on LED with the help of GSM

The project is to develop a system, which uses mobile technology that keep control of the various units of the automobiles, which executes with respect to the signal sent by mobile. Now a day’s every system is automated  in order to face new challenges in the present day situation. Automated system has less manual operation, so that the flexibility, reliabilities are high and accurate. Hence every field prefers automated control systems. Especially in the field of electronics automated systems are doing better performance. Probably the most useful thing to know about the global system for mobile communication is that it is an international standard. If you travel in parts of world, GSM is only type of cellular service available. Instead of analog service GSM was developed as a digital system using TDMA technology. For utilization of appliances the new concept has been thought to manage them remotely by using GSM, which enables the user to remotely control switching of domestic appliances. By a simple SMS sending to the GSM modem at remote place, the devices can be turned ON/OFF and the status of the devices can be sent to the mobile number .

Now-a-days  LED Displays are normally used in stationaries, railway stations, banks, etc. everywhere in the daily occupational life. This LED’s are pre-programmed in sense that they are already programmed to display ; in case of editing or manipulating the message a person is needed around the display either by leased media or some kind of wireless media(within a limited area) which itself is an disadvantage because a the person cannot be always present at the location of the display board; a person might be at some other place and it is urgent for the person to display the message on the LED  which is at a distant place, so this type of  LED Displays are not effective in all situations and also this display board cannot be placed anywhere because of complex and delicate wiring. “GSM based message decoder” is a model for messages decoder on led  within any networked area through SMS which can be send by mobiles. The Project aims to provide the services of communication with LED  remotely using GSM (that is by using SIM’s SMSs via mobile phones).
