Mobile Operated Notice Board

Description

• Notice Board is primary thing in any institution / organization or public utility places like bus stations, railway stations and parks. But sticking various notices day-to-day is quite a difficult process. A separate person is required to take care of this notices display. This project deals about an advanced hi-tech wireless notice board.
• The main objective of the project is to develop a wireless notice board that displays notices when a message is sent from the users mobile. While the user sends the message from the mobile, the remote operation is achieved by any smart-phone/Tablet etc., with Android OS, upon a GUI (Graphical User Interface) based voice operation. Transmitting end uses an Android application device remote through which commands are transmitted. At the receiver end, these commands are converted to texts used which are displayed on a 20X4 LCD – interfaced to the microcontroller. Serial communication data sent from the Android application is received by a Bluetooth receiver interfaced to the microcontroller.
• The program on the microcontroller refers to the serial data to display the received data on an 16*2 LCD.
• The power supply consists of a step-down transformer 230/12V, which steps down the voltage to 12V AC. This is converted to DC using a Bridge rectifier. The ripples are removed using a capacitive filter and it is then regulated to +5V using a voltage regulator 7805, which is required for the operation of the microcontroller and other components.
• Android based notice board for the good price for the engineering projects. It is very comparative engineering project. It is very good BE final year and Diploma projects. This projectcore electronics departments and electronics students in final year is use.For the last year engineering project for theelectronics department students is use this project is Bluetooth based project .
• Android based notice board using for themicrocontroller basedfor the good project, excellent project for the BE last year engineering student is use for the student is use and electronics and students is use. This project for the competitive project in the BE electronics Bluetooth based project last year engineering student for electronics student in last year engineering student in the use.
• Android based notice board it is the best projects for the electronics,final year student is use  and idea for the electronics and electronics degree and diploma base students and 100% output is done.
