4 Wheeled Bluetooth Controlled Rc Car

Tired of Joystick, Control with your phone. Uses L298n, Arduino UNO, HC-05 .

IntermediateWork in progress7,200

Things used in this project

Hardware components

Arduino UNO

SparkFun Dual H-Bridge motor drivers L298

DC Motor, 12 V

HC-05 Bluetooth Module

9V battery (generic)

4xAA battery holder

9V to Barrel Jack Connector

Software apps and online services

Arduino IDE

Hand tools and fabrication machines

Soldering iron (generic)

Story

This is my first project on Arduino cc. I have made the use of easily available components. I hope this project helps students.

Hello! In this project I will show you how to make a Bluetooth-controlled car which can be controlled through your Android smartphone!

Before starting, make sure that you have:

Arduino Uno board

L298n motor driver

HC-05 Bluetooth module or HC-06. they will have same connections

A Chassis

4 dc motors

For power supply I have used a 9v battery connected to Arduino uno Board and 4 x 1.5v cells

Android App

To control the car I have made the use of app called Arduino Bluetooth Rc car which can be downloaded from Play store.

Tips

First enable Bluetooth and establish connection with BT module (ex. HC-06, password 1234). Use the "Help & Info" button if you cannot understand how it is working.

Accelerometer function is under development, use with caution!

If you have problem with this app on your Android device, you can also use any other one.

Please share your innovative ideas.

"Learning and innovation go hand in hand. The arrogance of success is to think that what you did yesterday will be sufficient for tomorrow."

Code

Code for Bluetooth controlled car

#include <SoftwareSerial.h>
char t;
 
void setup() {
pinMode(12,OUTPUT);   //left motors forward
pinMode(11,OUTPUT);   //left motors reverse
pinMode(10,OUTPUT);   //right motors forward
pinMode(9,OUTPUT);   //right motors reverse
SoftwareSerial mySerial(0, 1); // RX, TX
Serial.begin(9600);
 
}
 
void loop() {
if(Serial.available()){
  t = Serial.read();
  Serial.println(t);
}
 
if(t == 'F'){            //move forward(all motors rotate in forward direction)
  digitalWrite(12,HIGH);
  digitalWrite(10,HIGH);
}
 
else if(t == 'B'){      //move reverse (all motors rotate in reverse direction)
  digitalWrite(11,HIGH);
  digitalWrite(9,HIGH);
}
 
else if(t == 'L'){      //turn right (left side motors rotate in forward direction, right side motors doesn't rotate)
  digitalWrite(10,HIGH);
}
 
else if(t == 'R'){      //turn left (right side motors rotate in forward direction, left side motors doesn't rotate)
  digitalWrite(12,HIGH);
}
 
else if(t == 'S'){      //STOP (all motors stop)
  digitalWrite(12,LOW);
  digitalWrite(11,LOW);
  digitalWrite(10,LOW);
  digitalWrite(9,LOW);
}
delay(1);
}
