How the Bluetooth Communication work in Arduino.

Basically the control of robot becomes easy through a Bluetooth module. Which means that the Bluetooth module and arduino is basically what you need to create a communication channel with a robot. There are a lot of Bluetooth modules but it seems that the HC-05 Bluetooth module is the most popular Bluetooth module for wireless communication in Arduino devices.

This HC Bluetooth module consists of two things.

• Bluetooth serial interface module
• Bluetooth adaptor.

Bluetooth serial module is used for converting serial port to Bluetooth. And the default baud rate of new Bluetooth module is 9600 bps which is also a suitable unit of transmission speed. Mostly in their connection type all we need to do is connect RX (receive) and TX (transmit) to controller or serial converter and give 5 volt dc regulated power supply to module.

But Bluetooth module cannot work on it own since it need a remote control device. Base on our project I think Android Smartphone is the best for a remote device since it the easies way to test the project. And there are a lot of application which are designed to enable the Bluetooth features of the device to make the connection with the Bluetooth module attached to the robot.

Here is a Bluetooth report on what we did during 6 weeks of Bluetooth project.
