To begin, I have never ever used an arduino to connect potentiometers, I only used real leo bodnar cards that have three inputs for each axis. Arduino seems only to use one pin, how is this possible?
But I followed the instructions
So now I have connected my card exactly as lightly described on the site here.
I want to use separate throttles = throttle 1 and throttle 2, and what I see is that there is only one throttle connection to pin 8, why?
Throttle 1 should go to one pin and throttle 2 should go to another pin.
But when I connected everything as said in the text on this site, https://www.737diysim.com/arduinomicro
And go to the game controller, all axis are fluttering and they only stop when I push a control button like engine start switch, A/T disengage, then everything freezes.
No buttons are reacting on the game controller.
What is happening here, the controler runs rock and roll when I connect it directly to my computer, no hubs nothing.
Why does this happen?
A potentiometer has three connections, +/-/GND, but here you only connect either + or - and the GND. Is it throwing a dice and use whatever here or what?
On a leo bodnar you connect a potentiometer to all three connectors for each axis
(I think it is much safer to use a real leo bodnar joystick board that spin around with this arduino leo bodnar look alike. At least it saves you a lot of problems)
Arduinos does not seem to be used as joysticks.....
Hi everyone! I´m trying to make the 9 axis to work on micro pro but only 6 work. I change the Joystick_Joystick axis parameters to true on the Sketch but windows game controllers only show six axis.
Another thing is that on the x and y axes, they only work halfway. Has anyone had this problem and know how to fix it?
Thank you.
Hi Karl, and everyone, hope you are all doing great, is there any help on how to connect rotary encoder for the trim wheel, instead of potentiometer? second questio is, is there a way to connect an LED light for the parking brake using arduino pro micro instead of connecting the LED with arduino mega as on the image
Hello Seb Pilot,
I totally disagree, an Arduino is basically a microprocessor that can do several jobs. One of those is potentiometer reading and is used worldwide for projects. A joystick is basically that. Converting analogue to digital signals (ADC). While the micro does have a lower bit resolution than a dedicated Leo Bodnar, it works perfectly across four axes. The micro is a known joystick card and is now used in many libraries. Just google it.
How much trimming did I do in my video, not sure to be fair, whatever was needed, but if jitter was there, I would have shown it? Jitter only came about after using 5-8 axis instead of 4 on the cheaper clone cards. This is why I now say use two micros.
I do believe that sticking with Leobodnar is probably best for yourself. However, for others who want a much cheaper joystick card, please do try it. At worse you will lose a few hours in design prototyping and at most 4 or 5 euros (and gain some great engineering, electrical and hand skill knowledge)
I'm pretty sure that most people will get this to work, after seeing how many people report back to this website.
Wishing you the best of luck with your project,
Kind Regards Karl
Tried the settings, and give up.
Trying to make an arduino to a reliable joystick controller fails.
Safety first is number 1 priority for me.
There is no doubt the arduino micro pro is not able to be a reliable partner as a joystick controller.
Stick with the Leobodnar BU0836X, it is very reliable and yes it is expensive but is also built for these builds. An arduino is not built for joystick controls.
Yes I know there are different opinions. But as in real life when flying, safety should be number 1. An arduino micro pro might work from time to time. But it is not reliable and stable. Fluttering and bad controls, no use.
To be honest, how much trimming have you made to your video when you calibrate the throttle v3?
I have spent a few days trying, and there is no chance to get it as stable as that in your video.
Arduino boards should be used for LED's and displays only in my opinion. Completely worthless for anything else that you need reliable and trustworthy.
Hello,
This has me most intrigued! How have you wired a potentiometer up with just one wire? You need three and the wiring diagram I have just checked shows that.
OH NO...! Are you using the axis jitter example as the whole wiring diagram? No wonder you are having issues.
Can I suggest that you look at the Wiring Diagram in the Wiring Diagram section:
For the Micro, you need page 2 of the throttle PDF.
You can see that each pot has its own dedicated axis to the Arduino, with each pot having three connections.
After speaking with several manufacturers, I would only recommend using the first 4 axis pins A0 to A3. This is because the resolution of the ADC is split between the further four pins causing jitter.
I really hope this helps you on your way. It sounds like you have your mindset on Leo Bodnar card. If that works for you, stick with it. I would suggest you use page 1 of the wiring diagram for the leobodnar.
Kind Regards,
Karl
