Description: This project is mainly based on mobile phone communication with the Microcontroller through Bluetooth, here we are using the Android based mobile, and to communicate with the controller we need the supporting software installed in the mobile phone. Bluetooth SPP software must be installed in it. Connect the Bluetooth module with microcontroller using the serial port communication. Then dump the following code in flash memory of controller, open the Bluetooth SPP software it asks for pairing with the Bluetooth module and after pairing the mobile with Bluetooth module then start entering the message whenever the message ‘3’ is entered and sent the relay will be switched ON and if we send ‘4’ Relay is switched OFF. Using the Relay we can switch ON /OFF the electrical device.

Role/Responsibilities: 

·      Implementing the full Embedded C Code for Bluetooth and sensor's like Temperature and heat by using protocols like I2C, UART, and ADC.
