Now a days advertisements are becoming digital. Big shopping centers are using the digital moving displays. In Railway stations and bus stands everything that is ticket information, platform number etc is being displayed in digital moving display. But in these displays if they want to change the message ,they have to go there and connect the display to PC or LAPTOP. Its major drawback of existing system. So keeping this in mind a new display system which can be accessed remotely, using the GSM technology to make the communication between microcontroller and mobile is designed.
We are using phone to send SMS for updating message on scrolling LED board. The SMS will be received by GSM Modem. The data is processed by microcontroller. The microcontroller used here is Arduino Atmega328 which updates same text message on 2 feet LED scrolling board. The 16×2 LCD is also used to show the status of the circuit.
Software:
- ARDUINO IDE
- EMBDDED CPP CODE
- Proteus Simulator
Hardware :
- ATMEGA328 Microcontroller
- 16×2 LCD Display
- GSM Modem
- Scrolling LED Board (2 Feet)
- Regulated Power Supply
