Wireless Remote control car

Hello myominhein

Welcome to the element14 Community, we hope you enjoy it! I will move this over to the Arduino area as it is a better fit.

Thank you,

Jamie

I would use a servo instead of a motor for turning unless you have a toy car that has everything you need except the microcontroller.  I might do something like this with one my toy TC truck.  First take it one step at a time.

1st see if you can do simple task with the bluetooth device, that if you new to microcontroller.

Once you understand the basic then is just slowly hooking things up and writing and testing you code.  You can easy do it.  The hard part is on the phone/or any bluetooth compatible device.  If you have already writing code for android, then you aren't going to have have any problem.

Hi myominhein I agree with muffenme.

A servo is best for steering and it's always a good idea to start small and build things up. You should try and get your Bluetooth working in a simple situation.

Here is a link to my blog which shows a simple set up using an HC-06 to link an Android phone to an Arduino and control an LED:

I hope this helps

Hi,all of my friends I am ok with 5 volt DC motor and using software serial

pin over the bluetooth signal module.The things that I worry about is that

damaging my Arduino.The schematic pin that I connect shown,please take a

look and after that the code also.

Please advice to me.The code and circuit is not complete at all lefting

about sensor,LEDs and sound system and LCD display.

The code is like that...

#include <AFMotor.h>  //For motor Driver that produce enough current

#include<SoftwareSerial.h> //For Serial External Data  Command

SoftwareSerial mySerial(10, 11); // RX, TX

AF_DCMotor Motor1(1);

AF_DCMotor Motor2(2);

void setup()

{

  Serial.begin(9600);

  Motor1.setSpeed(255);

  Motor2.setSpeed(200);

}

void loop()

{

    if(Serial.available() >0)

    {

      char ch=Serial.read();

            if(ch =='C')

            {

                Motor1.run(FORWARD);

                delay(1000);

            }

            else if (ch=='D')

             {

                Motor1.run(BACKWARD);

                delay(1000);

             }

             else if(ch =='4')

            {

                Motor2.run(FORWARD);

                delay(1000);

            }

            else if (ch=='6')

             {

                Motor2.run(BACKWARD);

                delay(1000);

             }

             else if(ch =='8')

             {

              Motor1.run(RELEASE);

              Motor2.run(RELEASE);

             delay(1000);

             }

            else

             Serial.println("You are wrong!");

    }

}

The abstraction digram is like that..

Let me know if this is something that interests you....it uses wireless receivers and transceivers which can be a bit tricky to use but is well worth it in the end.

Each motor needs 2 MOSFET to protect your arduino board or you can get a board design to work with arduino to control motor. like http://www.ebay.ca/itm/Stepper-Motor-Drive-Controller-Board-Module-L298N-Dual-H-Bridge-DC-For-Arduino-/170926726867?pt=LH_DefaultDomain_0&hash=item27cc06ded3.  The link was added March 10, 2015.
