How to Control a Bluetooth (HC-05) With Arduino

Introduction: How to Control a Bluetooth (HC-05) With Arduino

About: The science of robotics fascinates me. Come my friends to experiment together.

Hello my friends in this lesson we will learn how to control a dc motor with our smartphone or tablet.To achieve this we will use a L298N motor controller and Bluetooth module(HC-05).

So let’s start

Step 1: Materials/Things You Need

Step 2: Wiring Diagram/Connections

Step 3: Code

The code is designed very carefully in order to understand by everyone. In the image I explain what I have written. If you face any problem please write your comment below and I will answer you as soon as possible.

NOTE

HC-05 uses the serial communication. So begin the serial communication by using the function "Serial.begin()". Set the baud rate as 9600. Before uploading the sketch to your arduino board, make sure to remove from pins 0 and 1 of arduino the jumper wires or else it won’t upload it to the board. This happens because PC and Arduino use the same communication when upload a sketch. After uploading the sketch, connect the jumper wires to your board.

Step 4: Android App

For this project I use this app. You can download it from here

You have to pair the HC-05 bluetooth module with your smartphone or tablet and then your device (tablet or mobile) with app in order to work. Don’t worry it is very easy.

Step 5: That's It

The project is finished. I hope you like it. If you face any problems please write your comment below and I will answer you as soon as possible.
