DIY ARDUINO BLUETOOTH CONTROLLED CAR :)

Hello, Guys! In this instructable tutorial, I'm going to make an Arduino nano based smartphone (Bluetooth) controlled car. All we know that Arduino is an excellent prototyping platform, principally because it uses a friendly programming language and there are a lot of extra incredible components that provide us great experiences. We can integrate the Arduino with different shields or modules and build fantastic projects. In this project i will show you how use the Bluetooth module to control a car through commands coming from a smartphone. So This car could be controlled via Bluetooth using any Android phone or tablets. This is an very interesting project. It's simple to make, easy to program the arduino and also a great project for all diy lovers like me. So don't waste your time and let's make this cool project with me.

Here's The Full Tutorial And Demonstration video :

Step 1: The Parts List :

Here's The Parts List:

1. Arduino Nano

2. L293D Motor Driver

3. HC05 Bluetooth Module

4. 18650 Li-ion Battery(2ps)

5. Old RC Car model frame

6. Male To Female And Female To Female Jumper.

7. Wheels(4ps)

8.Slide switch(1ps)

9. connecting wires

Step 2: Wiring Diagram/Circuit Diagram:

Here's the entire circuit diagram: click for circuit diagram

Step 3: Connect All the Modules & Soldering Wires:

First, we'll start off by connection the wheels into the model then soldering the motors then making the connection among all the modules.

At first, connect jumpers between motor driver and Arduino as follows .

D5>IN1
D6>IN2

D10>IN3

D11>IN4

Vin>5V OUT

GND>GND

Now Connect Bluetooth Module to Arduino And Motor Driver

Arduino --> Bluetooth Module :

TX>RX

RX>TX

Motor Driver --> Bluetooth Module:

5V OUT>5V IN
GND>GND

Now solder battery's positive wire to switch, then connect it to the motor driver and connect negative wire of the battery to GND of the motor driver.

Step 4: Mounting All the Modules:

Now it's time to mount all the modules. First, apply some hot glue mount motor driver. Next, we'll mount Arduino and BT module. Then mount the battery. After mounting all the modules connect front and rear motor wires to the motor driver according to the circuit diagram.

Step 5: Upload the Code:

First, remove your bluetooth module then connect the Arduino to your pc, then upload the code.

Step 6: Download the App & Connect to the Car :

Download the car controller app from google play store.

The app link: click here for app

Now Pair your Arduino Car to your Mobile phone in bluetooth setting on your phone
Open Aruino app Click 'Connect' button Select 'HC-05' or any name you set for your HC-05 .and finally Let's play with your own made car :) :)

Step 7: We're Done Now:

Finally, we're done now. Have fun with this Arduino smartphone controlled car.

the motor moves very very slow. I tried with nano and then with uno too..but same problem

[BibroB]

then there may be a problem in your battery or power suply.

[trickyjas]

what was the top speed you was able to achieve?. and what if i need more speed than what you was able to achieve?

[THEBEASTATFNBR]

Cant this is a simple code but if you want i could give you a code the i made just with l293d motor shield

In would like to do this for a school engineering project if that is ok with you, if so would you suggest any type of RC model frame?

[BibroB]

Yeah sure. Actually I use a old rc car's model frame .you can use same or you make the frame by own using acrylic sheets. Okey as soon as possible, I shall try to make another instructables to show you that "how to make the model frame " . thanks.

[sumitsharma0698]

When will you be going to make that eagerly waiting for that

[WeTeachThemSTEM]

Looks like you had fun putting this car together! I love the rooftop photos. :D Thanks for sharing!

[BibroB]

Thanks mam . Thanks for your lovely comments. I really enjoy my every projects ,and your that kind of comments give me more motivation for enjoying more fun .
