Super boulot continue comme sa

Merci

Hi, if I go with a Leobodnar board, do I still need to follow the Arduino portion of the video?

[@diysimstudio8225]

Hi,
No, you don't need the Arduino part with Leobodbar.

[@karlonicololampa8809]

Im not getting any input. Using pro micro. Followed the wiring diagram and not detecting any input

[@diysimstudio8225]

Did you used the right Arduino sketch? Have you photos of your wiring?

[@diysimstudio8225]

Can you send me a mail ? The address: [e-mail]

Tell me how to integrate a variable resistor into the circuit with arduino pro micro to change the pressure sensor pressure force (Load cell)

[@diysimstudio8225]

The value can be changed in the brake setting in Arduino sketch file.

[@Betoofast]

does the pro micro wiring also work with a nano rp2040?

[@diysimstudio8225]

No it won't work

[@jameswiggin2631]

What if you are using a 3 wire load cell? How would you wire this up to the HX711 amplifier?

[@diysimstudio8225]

I can't give you an answer, sorry. The pedal is only compatible with 4 wire load cell.

[@jameswiggin2631]

@DIY Sim Studio well I purchased some pro Micro boards and hx711. I guess I will try and find out. Just missing the green wire from load cell. I guess these are referred to as half-bridge strain gauge load cells.

[@josekremer2014]

Does this system recognize in all simulators? And with this system can I make any adjustments to the pressure of the load cell? Thanks !!!

[@diysimstudio8225]

Hello José. Sorry for the delay of the answer, I just read your message. Yes the Arduino (and Leobodnar) boards works with all simulator on PC. And the brake can be adjusted in the Arduino code and the game setup.

[@josekremer2014]

@@diysimstudio8225 thanks

[@bruxaodev2317]

What is the difference between the Load Cell Joystick Controller for Leonard R3? Can I use Leonard R3?

[@diysimstudio8225]

The Leobodnar is a little more accurate for the brake and more easy for the soldering, and all Arduino micro and Leonardo boards with Atmega32u4 will work.

[@1nvisum376]

Good day!! Is it possible to replace the potentiometer with a magnetic sensor or a load cell on the gas pedal??

[@diysimstudio8225]

Thanks 👍 I never tried, but I think it's not possible.

[@1nvisum376]

@@diysimstudio8225 It's cool to make a bolub like that, I would buy it with this option from you))

[@1nvisum376]

I like to do it myself) but I'm not strong in electronics)

[@racingaddict3719]

Great vídeo! where can i get the sketch file?

[@diysimstudio8225]

The Arduino Sketch is included in the pedal file.

Your shielded cable is doing absolutely nothing since you didn't ground the shielding. Next time save yourself a few bucks and just use regular servo wire.
