Voice Based Notice Board Using Android

Android Based Voice Controlled Notice Board

Notice Board is important thing in any institution / organisation or public places like bus stations, railway stations and so. But sticking paper various notices is a difficult process. For that person is required to take care of this notices display. This project is an advanced smart notice board.

The main aim of the project is to develop a wireless notice board that displays notices when a message is sent from the user’s android application phone or device which achieved by any smart-phone/Tablet etc., with Android OS, upon a GUI (Graphical User Interface) based touch screen operation.

While the user sends the message from the android application device, it is received and receives by the Bluetooth module at the display system. The Bluetooth will access password. It is then sent to the micro-controller that to displays the notice sent from the user on to the notice board which is equipped with a LCD display. It uses a 8051 micro controller

Voice Controlled Home Automation

 Android Based Voice Controlled Home Automation

In This Smaru Voice controlled home automation System helps to control the electrical appliances based on Voice input. Here Bluetooth device input signal from android App via Smaru Phone. This system is especially beneficial those who find it difficult to walk and operate the electrical switches to turn on or off the appliances. This Smaru system solves this issue as now the user just give voice commands to turn on or off the appliances. All these loads can be individually turned ON/OFF or all loads at the same time. This system solves the issue by interfacing a unit with home appliances that Normal switches these loads based on the input received from android device. The Android app also provides an effective GUI for providing this functionality.
This system makes use of microcontroller. The Bluetooth receiver is interfaced with microcontroller to accept the commands and then work accordingly. It operates the loads through a set of relays using a relay driver IC. Relays are used between loads and the control unit. This Smaru system thus can be used in many Area where domestic applications and in industrial setups.
