Arduino Bluetooth RC car

Welcome to the Technical Praveen, in this article I will disclose how to make Arduino Bluetooth RC car. this is an extremely straightforward and fundamental task from the Arduino. and furthermore a mainstream venture like Home Automation. there is a great deal of quest for this undertaking. thus, I choose to make the undertakings with all the directions needed to make it conceivable. what does it do? it moves as indicated by your guidelines which we will give you on your cell phone. what's more, you can utilize this RC vehicle robot in numerous applications, for instance, you can utilize this robot in your home to convey the food. or then again we can utilize this robot to clean our floor. this relies upon you where you can utilize this wonderful robot. to figure out how to cause the robot to please peruse the full article bit by bit. there is some table of content as given as follows.

1. What we will learn in this project.
2. How does it work?
3. Components Required to make the project.
4. Connection Diagram
5. Code of the project.
6. How to set up the android app.
7.  How to upload the program.

What you will learn in this project:-

• Serial communication:-

What is serial communication and why it required? We have a great deal of information in equal habits. for instance, in the event that I have the information "ASKONIZATION" must be moved, at that point we need 12 wires or 12 ways to move the information starting with one gadget then onto the next gadget. in any case, as we are utilizing sequential correspondence then the information organized in the Serially with the assistance of some move enroll and can be moved by a solitary wire. this is a simple and straightforward approach to move a ton of information with a solitary wire as opposed to utilizing different ways or wires.

• How to use Bluetooth module hc-05 with Arduino:-

As we examined in the above section about sequential correspondence now we will figure out how to move the information through Bluetooth utilizing serial communication. There are four pins in the Bluetooth module Rx, Tx, VCC, and ground. interface appropriately as per the given circuit outline. We will utilize the baud rate 9600 on which a Bluetooth hc-05 can speak with the Arduino. Bluetooth module HC-05 is anything but difficult to utilize on the grounds that we are having numerous libraries inside the Arduino IDE. which assists with composing the program.

 How does it work?

In the Arduino Bluetooth car the information send by the cell phone to the Bluetooth module hc-05 which is associated with the Arduino and the Arduino take choices as indicated by the information got through Bluetooth. in the event that you send a guidance for left from your cell phone, at that point the Arduino will send the guidance to the engine to move the right. however, you need to associate the cell phone with your Bluetooth RC car. what's more, there is an application that controls the touch feedback to any guidance.

 Components Required to make Arduino Bluetooth RC car

• Arduino Uno
• Bluetooth Module HC-05
• Jumper Wires
• Chassis
• L298N Motor Driver
• 12V Battery
