Electronic Notice Board Controlled By Gsm
This is a Gsm (SMS) controlled notice board project. The sms message sent by user is displayed on a LCD notice board. Here we use a gsm modem to capture sms messages sent by user. The user needs to send sms messages to the the sim number of sim card inserted in the Gsm modem. The sms is received by gsm modem and decoded in order to forward message data to the microcontroller. Once message is received it is then sent to the microcontroller which processes this data. On processing the data the microcontroller now grabs out the sms message body text and then it is displayed on the LCD screen interfaced to the microcontroller.
