Simple RC car for beginners (Android control over Bluetooth)

This is a simple project of Android Bluetooth Car with Bluetooth control. Arduino controller is used

To control the car used Android-device with a built-in accelerometer. Tilt forward - car goes forward, tilt to the left - car turns to the left, tilt back - car goes back. Speed of movement or rotation depends on how much you tilt the device. Sensitivity and value of the tilt set in the configuration Android-apps. Also are provided a normal way to control: the buttons on the screen. In addition to all I implemented the touch control. Total 3 ways to control the RC Car.

Capabilities of the device you can see on the video above

Step 1: Android device

Parts needed

1. Android device

The most important part - Android device with accelerometer and Bluetooth: tablet, smartphone and other... As an Android device, I used a cheap Chinese tablet "Ainol Aurora" with an external USB-Bluetooth module (because its not have own), connected via USB Host.

This is great! Thank you for the fantastic tutorial. Could the Arduino (uno) be controlled with an iPhone as well?

[tolik777]

Sorry, I don't know. I havn't iPhone

[fckingdavai]

Iphone doesn t have bluetooth connection, but u can try to control the RC with an wireless conection. U will need a wireless bee for arduino

[lubizz]

cool ..

thanks for sharing bro

[ufang]

nice work!
recently i was building a 2WD robot kit as well.
i used the L298N motor driver from http://www.sainsmart.com/sainsmart-l298n-dual-h-bridge-stepper-motor-driver-controller-board-module-for-arduino-robot.html.
it looks like the same items with which one you used.
but it came without any instructions.
would you like to provide some manual about it?

Thanks for sharing a very useful information as you provide best car for beginner.As toys is a best hobby while watching movies or playing other games so i use EB16 1:16 Scale Electric RC Buggy has all the features such as adjustable suspension, oil shocks, aluminum chassis, high precision receiver, power and many more.But this one is new for me so i wanted to get some more information about it from you.

[amal soman]

could you pls... explain about the programming and programming software used for arduino.....also explain weather it can be programmed more than once..!

Awesome

[berrymartin]

I was looking for this kind of tutorial on internet for few days.it was excellent and very informative. Its really very useful of all of users. I found a lot of informative stuff in your this.......Read more

Version 1.2: Added a new type of management: the virtual steering wheel. Fixed class Handler. Improvements in Bluetooth class.

Can you recommend a quad bridge dc motor driver? I'm thinking about starting a project that would involve 4 motors, i'm just a little hesitant about where to start. Thanks!

[tolik777]

Do you want control 4 motors independently? Each separately?
Two or four control motor channel?
If you need 2 motors, you can connect them in parallel. For this you can use L298

[hoamattroi]

thank
good

[my wookie]

will the arduino uno work?

[tolik777]

Surely

[serenya]

Esli est' zhelanie uiti ot read-only to mozhno, tol'ko chto bi na habre ona poyavilas' pervoi, inache copipast budet otklonen. Pro net micro s udovolstviem pochitau dlya teorii. Ya uzhe sdelal takuyu mashinku i est' nekotorie voprosi, no ob etom navernoe luchshe po russki i na vashem forume)

[tolik777]

Uze nachal pisat statyu dly habra po .NET. Pisat sloznee chem sobirat :)

[serenya]

Esli napisat' stat'u i vilozhit' ee, to snimut read-only i dadut pravo pisat'

[tolik777]

Nu pro eto v kurse. No uze kak-to pisal, potratil kuchu vremeni, a statyu otklonili. Da i stati pro etu CAR uze napisany i vylozheny na drugom saite.
Mozhet byt dlya habra napishu pro realizaciyu na .NET microframework

[claudiodicapua]

Tolik777 you explain perfectly, don't worry about english language, in the future the Russian and Chinese languages will be necessary for all of us.
Are two languages that I want learn, Russia and China has great talents unknown in software, electronics, and sciences, and I want recruit many of them to work with me in Brazil.

[claudiodicapua]

and The best people that I have pleasure to make friends and trust are Russians and Chineses, my grandfather has descendant of Chinese Mongolian, do you see a Japanese with 2 mts height

[power000]

i like it i will made this but i will need your help!

[tolik777]

If you have any questions - ask me. I'll try to help

[imkzh]

I thought you are a chinese, since you said your English is poor.
My English is poor ,too. And,I'm Chinese.
You are chinese, aren't U?

[tolik777]

No, I'm Russian

Nice work ! Just to mention, I didn't see any level shifting between the arduino and bt module. Most bt modules found on ebay use 3.3v I/O and Arduino uses 5v I/O. Normally, the pins are 5v-tolerant but just to be sure, use either a 3v zener diode in parallel or a voltage divider bridge.

[tolik777]

Yes, you're right. Many BT modules require 3.3V, for this you can use 2 resistors (voltage divider.. for example 1k and 2k resistors). At first, I also tried to connect the module via voltage divider, but it not working property. Long puzzled, then removed level shifter and BT work's fine! My module is HC-06. Perhaps for other modules required level shifter

[prakis]

Simple, cheap and Beautiful. Thank you.

[wdupond]

Nice, now you have to make two tanks with IR bullets and receptors !
Think about all the models in shelves that wait for that since years.

[satyeshu]

A beautifully crafted idea really...!!!

[YourLord]

excellent ! I would relive the kid in me through this

[afrenois]

superbe réalisation

[hogey74]

Fantastic!

А на хабре нет желания статейку написать?

[tolik777]

Chto to tut s kodirovkoy.
U dannogo proekta est' stat'i na russkom: CxemCAR prichem dlja varianta Arduino i dlja STM32. Sejchas sobiraju podobnyj proekt na FEZ Padna II (.NET Micro Framework). Esli poluchit'sja, to proekt s pandoj opublikuju na Habre, no u menja tam ekkaunt tol'ko dlja chtenija.

[Husham Samir]

Excellent work!!!
