Arduino Leonardo Usb Steering Wheel

Introduction: Arduino Leonardo Usb Steering Wheel

About: i am a nerd that makes stuff

I had an old usb steering wheel laying around that died, i had a freetronics leostick laying around so i made this.
i updated the bootloader to the official leonardo one.

Step 1: Bootloader Mods

updated the bootloader to the official leonardo one.
for the steering wheel you will need an arduino leonardo compatible board with the leonardo bootloader.
update these files in root folder >hardware > arduino > cores > arduino
i used i.0.5 of the ide

files to download : HID

Step 2: Code and Wiring

here is the code i used, edit it to suit your needs :)
void setup()
{
  Serial.begin(57600);
  pinMode(13, OUTPUT);
  joySt.xAxis = 0;
  joySt.yAxis = 0;
  joySt.zAxis = 0;
  joySt.xRotAxis = 0;
  joySt.yRotAxis = 0;
  joySt.zRotAxis = 0;
  joySt.throttle = 0;
  joySt.rudder = 0;
  joySt.hatSw1 = 0;
  joySt.hatSw2 = 0;
  joySt.buttons = 0;
}
void loop()
{
  Serial.write("DIY USB joystick V1 by the nerdling");
  joySt.xAxis = analogRead(A4)/4;
  joySt.yAxis = analogRead(A5)/4;
  joySt.rudder = analogRead(A3)/4;
  Joystick.setState(&joySt);

}


the wiring is what i used on my wheel, the throttle and brake wiring is what i used because i needed 2 pedals for 1 channel, try it out and see what you need to do to make it suit you

that's all i will tell you because that's all you need figure the rest out e.g to put it all in your wheel each one is your different

    Can I directly use arduino leonardo without any modifications

    Hello Author. Thanks for this tutorial. What about the HID files to download? Whenever I click on the link it fails to download the HID zipped folder. Can you clarify what is contained in this zipped folder, what we need it for and how do I get these files from you or from an alternative source online? Many thanks

    Hello.I have a question for you.With arduino and this code i have deadzone on steering?(Sorry for my enghish :) )

    Made this only using smartphone - no cost - working great. sharing all
    places because UNO steering wheel was in my future projects list. due to
    costs of commercial gaming wheels. Now using existing smartphone and
    app its super easy.

    Would this work with a Optical Incremental Rotary Encoder like this:

    no sorry, its based on the change of resistance
    the optical encoder looks like it outputs pulses based off position
    you could edit the code but im not sure how

    Thanks for letting us know. I'd would love to see a project done with an Optical Encoder.

    is the potentiometer used for steering and can we add a clutch and h shifter which is a diy one. and in the diagram for brake and throttle is potentiometer used or can it be used??

    Sorry, this might be not the best idea.

    In a specific configuration of the throttle and brake potis there will be

    a short circuit between GND and VCC.

    Or is this the reason why you are using another GND and this is not a problem?

    i used a different ground because it was closer in the diagram

    this is how i wired up the throttle and brake pedals, it works fine no short
    it should work with a different ground pin

    I cannot get this to work. I get the following error in the compiler:

    Controller_3.ino: In function ‘void setup()’:

    Controller_3.ino:5:3: error: ‘joySt’ was not declared in this scope

    Controller_3.ino: In function ‘void loop()’:

    Controller_3.ino:20:3: error: ‘joySt’ was not declared in this scope

    Controller_3.ino:23:3: error: ‘Joystick’ was not declared in this scope

    what Code do you have before "void setup()"

    I swapped out the files in the root folder and used your code. Won't work...

    any suggestions? I am also using arduino 1.0.5

    use arduino 1.0.1. Modify the root files as this tutorial states, but for arduino 1.0.1. Secondly, make sure you have the Leonardo selected as the board you are using.

    I cannot get this code to work for any other versions of arduino accept arduino 1.0.1.

    link to all older arduino versions: http://arduino.cc/en/Main/OldSoftwareReleases

    did you put the files in the root folder, eg "arduino-1.0.5" or in these folders?

    root folder >hardware > arduino > cores > arduino

    Would a version of this work with an arduino mega? I am rather new to fiddling with Arduinos, got a mega 2560 from a friend and I have a busted steering wheel as well.

    I don't think it would work
    is it can act line a USB keyboard then yes it might
    I used a freetronics leostick with the Leonardo boot loader for my steering wheel

    Thank you for the reply, after your comment I went googling and there are indeed ways of making the Mega work as a usb HID device, I might do some stuff and try to use your code while I wait for the rest of the hardware I bought for a different project with the same arduino.
