Arduino and HC-05 Bluetooth Module Tutorial | Android Smartphone & Laptop Control

In this Arduino Tutorial we will learn how use the HC-05 Bluetooth module for controlling Arduino via Bluetooth communication. For this tutorial I made two example, controlling the Arduino using a smartphone and controlling the Arduino using a laptop or a PC. In order not to overload this tutorial, in my next tutorial we will learn how we can configure the HC-05 Bluetooth module and make a Bluetooth communication between two separate Arduino Boards as master and slave devices.
