Introduction to and use of the Arduino The Arduino is an open source community working on hardware and software development.We can say that both hardware and software help in building new segment automated devices such as 3D printers, projects based on various parts of information technology, etc.<\/p>

Arduino software is used to generate code for every project made using any Arduino board; mainly uses the C \/ C ++ language for its encoding.<\/p>

When the code is ready, we just need to compile it and load it on the board for our project to work.<\/p>

There are many types of Arduino boards such as Arduino Uno, Arduino Nano, Arduino USB, etc. In this project we will use Dasduino board.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Bluetooth HC-05 is a Bluetooth module that is mostly used in the Bluetooth based project. It is easy to operate and can be easily configured with the Arduino.<\/p>

It has two operating modes: Command mode and Data mode, as we can change these modes by just pressing the push button on the Bluetooth module. It has Six terminals. Two terminal are Vcc and GROUND for power purpose.<\/p>

The other two are TXD and RXD, the transmitter and receiver; respectively, these are the terminals that send and receive signals from the Arduino board to control the device. The other two terminals are State and Key, which tells the state of the module that it is in command mode or data mode.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t
