Arduino Joystick 2.0 Library - Beginners Guide

[@CRJ700]

I have decided that YOU are one of my favorite people in the entire world! Not just because you've got that cool accent thing going on, but because you posted something useful that went straight to the point. Thank you for saving me TONS time by posting this tutorial. It is VERY appreciated!

[@Johan-ex5yj]

This is an excellent tutorial, thank you. 👍 One possible improvement is to add the following in the setup section >> Joystick.setXAxisRange(0, 255); Joystick.setYAxisRange(0, 255); Joystick.setRzAxisRange(0, 255); Joystick.setThrottleRange(0, 255); That ensures that you get full range output, with no need to calibrate.

[@CapungPlastik]

what's the different using "range" and map?

[@Johan-ex5yj]

@@CapungPlastik In this example the guy is mapping the normal 10 bit analog range of 0 to 1023 to 0 to 255, because he wants the resolution to be bigger (less sensitive). The Joystick library, expects (by default) that the numbers will be 0 to 1023, so you will end up with a Joystick that has only 25% of if it’s full travel. That is why you need to specify that your range is 0 to 255. If however, you use the full 0 to 1023 resolution, you don’t need set the range, and you also do not need to do any mapping. In this case the range command is still useful if you need to invert an axis, then you go: …Range(1023, 0) instead of …Range(0, 1023) .

[@garethbarry3825]

Just one thing for anyone who-like me- comes here to use this tutorial to build a joystick or button box - the 'ResponsiveAnalogueRead' library is incredibly useful - it helps get rid of the 'jitter' that is often a problem with potentiometers and other analogue inputs. The examples in the library itself show quite clearly how to implement it.

[@Magpie...]

Oh mate, I've been tearing my hair out trying to get hall sensors to work well. I hope this does it!

[@garethbarry3825]

@Magpie... give it a try (responsiveanalogRead), it made a HUGE difference for me! Also, try to make sure that the power supply is as stable as possible-if you look at the power cable to something like a thrustmaster joystick, there is often a ferrite ring, which is also get rid of any noise on the power line. Try using shielded cable from the arduino to the hall sensor signal pin, with the actual shield (the mesh wire around the signal wire) grounded on one end. Another thing that can help is a small capacitor from the power pin to ground to act as a low pass filter. I feel your pain- it took me ages to get the hall sensors in my home-made throttle to work well. In the end, the responsiveanalogRead library fixed the problem completely, without having to use shielded wire etc. Have you tested that you are getting nicely changing values on the serial monitor when you move the sensor relative to the magnetic field? Let me know is there is anything I can help with- i hope you have success!

[@garethbarry3825]

@Magpie... i typed out a reply which got deleted for some reason, but, as well as ResponsiveAnalogRead, you can also 1. Use shielded wire from the signal pin of the hall sensor to the arduino. Make sure that the actual shield is grounded on one end. 2. A small capacitor between V+ and ground to help smoothen the voltahe supply. 3. A small capacitor from the signal wire to ground. Note; both 2 and 3 act as low-pass filters to smoothen and stabilise a voltage. The larger the capacitor value, the heavier the filtering. Im sure that ResponsiveAnalogRead will go a long way towards solving your problem

Now that was a brilliant video - unfortunately I still cant get around my problem, so hoping you can give me a pointer? So I have a 6 point rotary switch. Between the output pins on the switch I have soldered 2k resisters, so each time it is switched a different voltage is set sent to the Leonardo. So the 6 outputs use only one pin on the card. Though I can create a sketch that tests the serial output to monitor, I can't figure out how to incorporate it into a joystick - is it a zRotation like your slidders?

Awesome video. Once you program the board, can you still reprogram it with the IDE if the USB controller still thinks it is a Joystick?

[@agenchicken]

Nice video man good job and ty for helping us! If I can ask you if you can explain how the steering and brake work and how we can use this library for making a steering wheel and if I can. Ty for everything and also you have a really nice voice!

[@danstechbox7077]

Thanks for the complement! I do actually do some voice work at times! As for your question, thats fairly straight forward. Instead of defining the Axis as X,Y, Rz, and Throttle as I did in the video, you can define the axis as any of the avalible in Windows HID, as shown in the avalible axis when you define your joystick (I have them listed out in the example code in the description). In your case, you could make a pedal set using Accelerator and Brake as Axis, with possibly a Digital Button for a Clutch (depending on your use case), and then using the Steering Axis for the steering wheel - really depends on how complicated you want your setup to be. The reason you would use the Steering, Brake, and Accelerator axis as opposed to just using an X and Y axis on seperate physical units (such as two potentiometers) is that Windows joins these two together - the Steering, Brake, and Accelerator axis are reserved axis, and are seperated in the HID system so they dont have any dependancies on eachother. While most games can seperate them, there is no guaruntee as different generational implementations of the HID system can get veeeery messy, so it is better to approach it correctly from the HID controller end to avoid any overlaps in the HID software and game decoding. You can pretty much use any potentiometer, or even magnets and Hall-Effect sensors (Will be doing another video on that now my 3D printer is working again), to give you an analog input, however you will need to add a hardware return device (such as a spring or something) to make sure it goes back to reading the middle of the axis, however there are some deadzone tools in both the Windows HID setup and the Joystick 2.0 library (I think) to enable a wider middle section if you cant get an exact centre and find your wheels/rudder/other steering device is slightly leaning when it should be central. This is something I would like to approach in another video with my own Joystick and Flight Control system, but I'm still designing that so in the meantime that should give you a good idea of what to consider when designing/building your own steering wheel and possibly pedal set. You can also make digital buttons work as analog axis at 100% using some clever coding, which I will do in another video shortly, if you want to have a button on the steering wheel for brake but dont want to use a digital button, and would rather use the Brake Axis - but that depends more on how you're building your steering wheel and what games/software you want to use it on. Hope that answers your question well enough, but let me know if you have any more specific questions or would like me to clarify anything.

[@agenchicken]

@@danstechbox7077 Yeah ty for all of the information is really helpful but I have 1 more question I have no problem with the steering wheel and pedals with an optical encoder and potentiometers but the strange thing is in the game f1 2020.

[@chiragjeram]

thank you sir for nice video, can you guide how can i use yours' beginner guide sketch to make 1 joystick and 20 push buttons on arduino leonardo?

[@danstechbox7077]

Hi Chirag Jeram! Thanks for the comment. Hope i can answer your question properly. To use the arduino leonardo, you literally just need to change the board - the only difference between the two in regards to this project are the number of pins and the pin numbering. Nothing in the code would change apart from adding in the extra buttons and removing your unused axis. HOWEVER, although the technical spec says that the board has 20 Digital Pins and 6 Analog pins, a number of these pins are shared due to the nature of the chipset, and as a result you can have a maximum of 20 Digital Pins, 14 Digital Pins and 6 Analog Pins, OR Any variation of the above. For this kind of setup, you would be limited to 18 Digital Pins for buttons, and 2 Analog pins for the X/Y of the joystick. If you reeeally need 20 buttons, you could either go for a button matrix (more complicated option) or swapy the board out for the Arduino Due, which has significantly more Digital Pins, but that may be overkill depending on your project. Below I'll go into the changes for the code, regardless of your board choice (I wont go into button matrixing as that is a video unto itself) In the Joystick Initialisation section, reduce your axis to just including X and Y, everything else for false, and change the number of buttons to 20 (or however many you want). For the Joystick - In the beginner Guide Sketch, you would use the X/Y axis of the Joystick as A0 and A1, set up with the hardware how I wired the joystick up in the video - Just comment out or delete the "#define joy####" lines with whichever axis you dont wish to use, and likewise the Axis Initialization and Axis Reading sections for the axis you are not using. For the Buttons - Duplicate the "#define joyButton####" lines, changing the button number and pin inputs for your buttons to the button number (in this case 1-20) and the pin you are putting it in to in the Arduino board. Likewise, set up the "pinmode" of the extra buttons as demonstrated for button 1-3 in the code, and make sure to do the same for the "LastButton#State" section per button, or none of them will work. You will then need to copy the "Current Button State" IF loop per button in the "Button Reading During Runtime", changing the button Number for every copy. If you want to, rather than copying them individually, you could subnest the IF loop and do a for loop to cycle the test between buttons 1 and 20, but only if you feel confident doing that. Otherwise, everything else should be as it is in the video. Let me know if you have any more questions.

Great tutorial! Btw, I've read some other examples. they have different values for the "set Axis" like (-127,127), (0,255), (-512, 512), (0,1023).. any info on this and what value should we choose? regards

[@Johan-ex5yj]

That is probably related to the mechanical limitations of the setup. Example: You have built your own rudder- pedals. The travel in the potentiometer you are using is limited, only giving a voltage output from 1 to 4 volts (not 0 to 5 volts). If you put this into your sketch (without any range or map) and print out the values you are getting, it will be something like 204 to 818. The rudder in your Simulator (expecting 0 to 1023) will not turn its full range. So what you do to fix that, is set the range like this: Joystick.setRudderRange(204,818). Then everything will work fine.

[@CapungPlastik]

@@Johan-ex5yj Hi, sorry if discussing this within the comment section. So I build a wireless drone simulator dongle using this library for the input. Its recepting values within 0-1023 for AETR input. While other simulator accepting the input as like in the game controller tab (after calibrated), some other simulator only works on certain values of input. like 0 to 127 or 180 to 360.. eventually I could manage this using Range and mapping, but when I connect the module to Android, it needs 0-1023 input. So using a mapped values will limit the stick movements. So, is there a way to recognize or manage the input for different device or OS (computer and mobile phone/Windows and Android)? (beside adding a button to switch value based on device 😀) Regards

[@Johan-ex5yj]

@@CapungPlastik Yes, if you have simulators that expect other input ranges than the standard 0- 1023, you will have to use different range settings in your Arduino sketch. If you want to use the same Arduino micro for these different simulators, I would add a DIP switch connected to some digital inputs as a way to select the range to use. If you are developing your own simulator- interface in Windows or Android, you could use the serial port that the Arduino provides to communicate to your Arduino sketch to specify what range you want to use.

[@Johan-ex5yj]

@@MonicaYap Do not calibrate, use the min/max numbers obtained from Serial.println(Val) command in your sketch, entering them into Joystick.setRyAxisRange(Min?, Max?) afterwards. If this still gives too poor resolution, you need to find pots with smaller electrical angle (90deg or less), as is used in joysticks. Another way to go is to use Hall Effect Sensors.

Hey dude, Amazing video, helped me so much. Im running into a little bit of an issue, i dont know if maybe you can help me. Im currently making a button box for xplane, and to do a test i just connected a toggle switch to the arduino micro and made a joystick (exactly like you did) but with only one button, uploaded the code and tested on the windows manager for usb game devices, everything was working.However, when i connect the arduino micro and go into Xplane the game freezes, do you have any idea what can be causing this issue? Thanks in advance

[@danstechbox7077]

Glad it helped you! It could be a number of things. I know XPlane has a few reserved USB device ID's, so you might need to change the device ID as I outline in the video to something further along, just to ensure that it's not clashing with anything. With Toggle Switches, it could be the continous signal - in a few of my games I know i've seen this issue. I am currently working on a function module to take a toggle switch and get the code/windows to treat it as two discrete button presses, but I'll need a bit of fiddling to make sure it works, and likewise will also require some input on the user end to make sure that the switch position matches up with the simulation position. For now, try removing the toggle switches and using push buttons instead - see if that get's XPlane to play nice. Otherwise, try shifting the USB device ID along a bit in case you've hit a reserved value. Hope that helps.

First of all I would like to thank you for providing such an informative and useful video. Really!! Actually I was planning to make a arcade joystick using a keyboard encoder taken out of a usb keyboard. But using a Arduino Leonardo looks much efficient and better. I have some questions!! I am planning to make a Mame arcade encoder with 4 direction keys + around 14 other keys to play and control the settings of Mame. As you know, in arcade fighting games, we press multiple keys simultaneously ( for example, up+right+ button 1 etc), will it be possible to do so without any delays? In computer keyboards, when we press multiple keys, we have problems such as keyboard ghosting and masking. So Arduino leonardo keyboard encoder will have the same problems?

What would I need to add to set a deadzone?

[@FERNANDOPENAS]

How do I declare multiple buttons in a single input in this code? I understand the wiring but do not know the code.

[@Stratlegend]

Very good tutorial, but 1 question. In the Set up USB game controllers the joystick recognized for calibration and use only hen the arduino ide sodtware runs. If the IDE close the controller stop working. Maybe stupid question, but why this happend? Need also software for communication? Thanks!!!

[@toyoboi]

you should make another video. I'm working on my first project (a 6 DOF joystick using a stewart platform) and I'm struggling with quite a bit.

[@yeloyoung9944]

does it works on arduino uno?

[@lironkalfa5479]

I can use a 3 analog joystick?

[@malejvelkej_]

Hi, i have maybe an issue, when i'm in the game controler properties and i have for exmaple throttle and z rotaion set in the code and when i turn the potentiometr it moves with both of the values please help

[@brianpaavo8192]

Thank you very much. This was a great video for the first steps, I've successfully created two arduino leonardos each with several buttons and potentiometers. I'm clearly missing something at the end (as I see other commenters have)...I have created an alternate boards.txt file, altered the name, pid, and vid, then uploaded the sketch to one of the leonardos. When I open USB controllers to calibrate I only see one leonardo even though both are plugged in. There's something seeming skipped quickly past on creating a ?second? hardware directory? Went through several times...can you expand on that step please?

[@brianpaavo8192]

Renaming a second Leonardo is much more complex now. On Windows10 the ACTUAL boards.txt file is in the WindowsApps folder which is one of the most heavily protected locations and uneditable without complex permissions changes which are dangerous for other windows apps. The intermediate solutions seems to either use a Linux system OR us an earlier non-admin installation of the IDE. Working on that now.

[@Johan-ex5yj]

@@brianpaavo8192 My Arduino Pro Micro can be programmed as a Board: “Arduino Leonardo” ; or as a Board: “Arduino Micro”. Both works fine as a Joystick. This gives you 2 different names in Devices. *(and that is just using the standard installation, without adding a boards.txt of your own)* I do not have 2 Arduino Pro Micro boards so can’t test if both will work at the same time. But this is something you can try, and please report back to say if this is a good alternative method.

[@tnpotomacrr4792]

It seems I was able to change an Arduino Micro name by finding the boards.txt in the Hardware folder that resides in the Arduino IDE program files. When I added my own boards.txt under the documents/Arduino/Hardware, the boards.txt there was ignored and uploading the sketch would revert back to the boards.txt in the IDE’s program folders.

Excelent tutorial, the best i found to get and idea of how to have a HID joystick with an Arduino. My question would be, is it possible to wire 32 buttons and four axis to the Leonardo? How?. The library allows it, but don´t know if it is possible with the board.

[@danstechbox7077]

The Four Axis wouldnt be an issue with the Leonardo, however with the buttons you'd hit the pin limit pretty quickly. The way I see it, you have three options: 1) Get a board that has the right number of pins AND is USB HID complient and do a One-to-One pinmapping approach - in this case you'd be limited to the Arduino Due 2) Do a Row-Column approach for the buttons using standard keyboard matrixing - there are several guides on how to do this online. 3) Use a Button library, such as AceButton, which has compatibility for Binary button mapping (using base 2 binary as pin inputs) - you'd only need 6 pins for 32 Buttons, in this case. There are approaches using resistor ladders and analog inputs, however depending on your board and other circuitry, this could just complicate things, especially if there's any noise on the wiring or switches. I personally would consider looking at the AceButton library for this, as it has excellent de-bouncing support for button presses too - however, if you want to keep your wiring and code simple, get an Arduino Due. They're avalible on Ebay for about £10-£15 a board. I will be doing a video at some point soon about Binary Button Mapping as I think it's a very valid approach in comparison to Row-Column matrixing.

[@Tom_GTom]

I think this should work for your issue. www.instructables.com/How-to-access-5-buttons-through-1-Arduino-input/

@@Tom_GTom Thanks Tom for the link. Reading it now.

[@lancelot4915]

@@danstechbox7077 Thanks for the answer, after some reading, i finally decided to go with the matrix. The third option is completely new for me, but i will start to research about it now,. At first glance it seems the best solution.

[@andrewjamez]

hi there thanks for your tutorial, Are you able to name your device? for example I am building flight sim controllers and want the name of the controller to show in the joystick calibration menu and not just "arduino Leonardo"...

[@jason6344]

I am very new to this and trying to make a joystick that emulates a controllers left analog stick. I have a joystick module and am soon to get a leonardo board . I am not so sure what to do past this.

[@danstechbox7077]

If you watch the video and follow along with the way I've wired up the joystick, and when you're defining the code you only need to have the X and Y axis included (along with a button press if you want that in there too), that should do the job.

[@simtcr]

Will this work with a esp8266 nodemcu?

[@technicahmett]

Good job dude. Thank you... Firstly I try it quickly on files in my Arduino IDE, but didnt work. Then I try again your uploaded files and it is work. What are the differences?

[@danstechbox7077]

Are you trying the example code in both instances, or is your own code not working, and then my code is? One of the ways I troubleshoot my code is I use the compile/verify feature to check my code for basic mistakes prior to upload - its the little check-mark button next to the upload button. Make sure your board is selected in the tools menu, and then when you verify, it should give you a little diagnostics panel at the bottom. The orange text is the errors, and it should highligh the location in the main body of the code as to where the error is - this should give you a better idea of what's going wrong with your code.

[@technicahmett]

@@danstechbox7077 That is not code. That is your uploaded files (AVR, bootladers, boards)...

[@danstechbox7077]

​@@technicahmett Aaaah sorry, got a bit confused there. The boards.txt definition was simply a descripter/payload for the bootloaders - in this case it redirects to the Caterina-Leonardo bootloader within that file. If your stock bootloader isnt working, that sounds like an issue with the Arduino IDE's stock/default bootloaders, so it might be worth removing them in file explorer and re-installing them via the boards manager in Arduino IDE. Otherwise, a fresh install of the IDE should fix that issue, but make sure to make note of your installed libraries as they can sometimes be removed in the uninstall process.

[@technicahmett]

@@danstechbox7077 I copied to under my doc folder from Arduino folder. But dont work. but no problem friend. I downloaded your files and it is ok. Thank you...

[@stevling1]

I'm a bit new to this how do I update that boards.txt file so it works in newer versions like 2.2.1 thangs for the Guide :D

[@dylans4776]

Would you happen to know how to hookup a 3 position switch (mainly the coding for that) I’d like to use it as a flaps switch

[@Johan-ex5yj]

Assuming a centre- off- 3 position switch and using A2 input and RzAxis. Connect a 10kΩ resistor from A2 to Vcc Connect a 30kΩ resistor from A2 to Gnd Connect top terminal of switch to Gnd Connect middle terminal of switch to A2 Connect bottom terminal of switch to Vcc In your Sketch: In the setup section use: Joystick.setRzAxisRange(0, 1023); In the loop section use: Joystick.setRzAxis(analogRead(A2) - 512); This should give you (in your flight sim) a control surface that is centralized when the 3 position switch is in up position, half way down when switch is in middle position, and all the way down when switch is in down position. If your control surface is moving in the wrong direction, simply use Joystick.setRzAxisRange(1023, 0); instead.
