HC-05 Serial Bluetooth Module

HC-05 is simple and in-expensive serial(UART) to bluetooth adapter. The HC-05 is an expensive module that is compatible with wide range of devices including smartphone, laptops and tablets. Adding a Bluetooth to Arduino can take your project to the next level. It opens up lots of possibilities for user interface (UI) and communication. The phone/tablet etc can act as an UI element or data logger and interpreter for your next project.
