Sending messages from the remote phone to the electronic board 9. Interfacing of the mobile phone with the programmable chip5. Interfacing the programmable chip with the electronic board display4. Interfacing the programming chip with the personal computer3. Programming of the mobile phone with AT (Attention) command sequence2. TheAT commands are serially transferred to themodem through MAX232.The microcontroller will read the messagefrom serial headphone and verify for thepassword, if the password is correct then itwill start displaying the messages in thedisplay system 7. METHODOLOGYUser wants to display a messageUser sends the message in his mobile definingthe messages and then the password of thesystem to the number of the subscriberidentity module (SIM) which is inserted in thedisplay system MODEM. COMPONENTS SOFTWARES Microcontroller (8051) GSM Modem SIM LED MATRIX MAX 232 Power Supply Keil u Vision Flash Magic 5. Displays are designed to quickly display theinformation in the light emitting diode matrix display. Public can send flash information from Mobiles todisplays for instant viewing.
