Even user can set module’s setting by using AT command. User can set either mode by using some AT commands. You just need to connect rx and tx to controller or serial converter and give 5 volt dc regulated power supply to module.īluetooth module has two modes one is master mode and second one is slave mode. Default baud rate of new Bluetooth module is 9600 bps.
You can directly use the Bluetooth module after purchasing from market, because there is no need to change any setting of Bluetooth module. Bluetooth serial module is used for converting serial port to Bluetooth. HC-05 Bluetooth module consists two things one is Bluetooth serial interface module and a Bluetooth adaptor. So that microcontroller can Turn ON and OFF the home appliances accordingly. Here we have used 8051 microcontroller with a Bluetooth module, for wirelessly receive the data, sent from the Android Phone. We have also developed a Toy car controlled by Android Phone, using Bluetooth module and Arduino. Bluetooth has a range of 10-15 meters, so that you can switch ON and OFF any electronic appliance within the range. Imagine that you can control the electronic appliances of your home from anywhere inside the house, just using your Smart phone. In this project, we will use wireless Bluetooth technology to control the Home Electronic Appliances through a Android Phone.
