  •  GSM based advertise dispaly

Aim:

To Roll the advertisement display via SMS

 

Working Principle:

To Roll the advertisement display via SMS. Here the user can send the advertisement matter via SMS. The User has to type the advertisement material on his Mobile and send to the pre saved number of GSM Modem. The GSM modem received the SMS and sends it to the µC.

Block diagram Explanation:

Here we are designing a System which will automatically receive and read the SMS from GSM modem using “AT” Commands. The “AT” Commands (Also known as Attention commands) are used to read and send SMS via GSM Modem. The user has to send the SMS in a particular format. Here the user can send the advertisement matter via SMS. The User has to type the advertisement material on his Mobile and send to the pre saved number of GSM Modem. The GSM modem received the SMS and sends it to the µC. The µC reads the SMS via GSM Modem and Rolls the SMS on LCD.

  • Is SMS Received? Yes, Read the SMS from Modem
  • Store the SMS in µC internal memory (RAM).
  • Display and the SMS on LCD
