"Bonibon" Bluetooth_Controlled_Car

Today, ı wil made a RC Car with arduino UNO and some supplys. You can easly make your RC CAR and have fun. Let's look steps...

Here is a list of parts that i used to make this project:

• Arduino UNO
• HC 05 Bluetooth Module
• L298 Motor Driver
• 2*DC Motor
• On/Off Switch
• Jumper Wires (male to male and male to female)
• 9V Battery (i use 10* 1.2V lipo battery)
• Drunk Wheel

The code has explanations of code functions. You will easly understand it. If you have a problem , you can contact me.

const int in1 = 9;      //BACK RIGHT
const int in2 = 8;      //FORWARD RIGHT  
const int in3 =  10;    //FORWARD LEFT
const int in4 =  11;    //BACK LEFT
const int enA = 5;      //left motor speed
const int enB = 6;      //right motor speed
  //!enable pins have to connect with arduino's PWM pins!
int yavas=200;          //decrease the speed(you can just chance here ,not every code); 
void setup() {
  pinMode(in1, OUTPUT); //all motor pins are output
  pinMode(in2, OUTPUT);  
  pinMode(in3, OUTPUT);
  pinMode(in4, OUTPUT);
  pinMode(enA, OUTPUT);
  pinMode(enB, OUTPUT);
  Serial.begin(9600);    //for serial communication
}
void loop() {
  if(Serial.available()>0){     //if we communicate with hc 05 
   char durum = Serial.read();  //get the input 
}
   //FORWARD
    if(durum=='w'){               //if we get 'w' 
    analogWrite(enA,  255);       //set left the speed(0 to 255)
    digitalWrite(in1, LOW);       
    digitalWrite(in2,HIGH);
    analogWrite(enB,  255);  
    digitalWrite(in3,HIGH);
    digitalWrite(in4, LOW);
}
    //TURN RIGHT

     analogWrite(enA,  255);  
    digitalWrite(in1, HIGH);
    digitalWrite(in2,  LOW);
    analogWrite(enB,  255);  
    digitalWrite(in3, LOW);
    digitalWrite(in4,HIGH);

    //TURN LEFT SLOWLY
    if(durum=='m'){
    analogWrite(enA,  yavas);  
    digitalWrite(in1,HIGH);
    digitalWrite(in2, LOW);
    analogWrite(enB,  yavas);  
    digitalWrite(in3,HIGH);
    digitalWrite(in4, LOW);
}
    //BACKWARD SLOWLY
    if(durum=='n'){
     analogWrite(enA,  yavas);  
    digitalWrite(in1, HIGH);
    digitalWrite(in2,  LOW);
    analogWrite(enB,  yavas);  
    digitalWrite(in3, LOW);
    digitalWrite(in4,HIGH);
    
}
    //STOP THE CAR
   if(durum=='z'){              
    digitalWrite(in1, HIGH);    //if we make HIGH every pin it will stop
    digitalWrite(in2, HIGH);    //or you can do :
    digitalWrite(in3, HIGH);    //analogWrite(enA,0);
    digitalWrite(in4, HIGH);    //analogWrite(enB,0);
}
  }

I use Arduino Bluetooth Controller for communicate with HC 05 module. You can figure buttons like you want.

Also you can use this application some other projects...Here is the some clues for you:
