Wireless Notice Board Using GSM

The wireless notice board is a very selective term for this project, as it has a very wide scope rather than just being a simple notice board. First, we should understand the purpose of this project, in this system, we can display a message or notice to some display device like LCD, and this message can be easily set or changed from anywhere in the world, just by using the SMS facility of your mobile handset. Whatever notice we want to display, just send the SMS of that text, with some prefix and suffix.

This is very useful in Hotels, Malls, college, offices and can be used anywhere, even at home. Like you can set the message like “Do not disturb” at your hotel’s room gate, can set message at your home’s doorstep when you are away, and of course, it is used as a notice board in schools, colleges, cinema halls, etc. And yes, it’s just not a simple Message board, the usefulness of this project is that you can set or change the message or notice from anywhere, just sending SMS from your phone.

Step 2: Circuit Diagram

Connections of Wireless Notice Board using GSM and Arduino are simple and shown in the figure below. Here a liquid crystal display (LCD) is used to display a message, which is sent through the mobile phone as SMS. Data pins of LCD namely RS, EN, D4, D5, D6, D7 are connected to Arduino digital pin number 7, 6, 5, 4, 3, 2. And Rx and Tx pin of GSM module is directly connected at Tx and Rx pin of Arduino respectively. And GSM module is powered by using a 12-volt adaptor.
