    Hi. I have a simucube that I bought 10 days ago.
    I want to connect buttons to raise and lower gears, or for other options.
    I want to connect potentiometers for accelerator, front brake, rear brake.

    I have seen this page:
    Http://granitedevices.com/wiki/SimuCUBE_connector_pinouts

    Http://granitedevices.com/wiki/SimuCUBE_wiring_overview

    Viewing this page as I do not know much about electronica, I do not know how to connect them.
    I would like someone to tell me graphically how they would connect. And as it is configured in simucube software.

    Do you recommend directly buttons, potentiometers to simucube or use a leo bodnar plate or similar?

    A greeting.

    I self-answer my message. JEJEJE.
    This is the answer from the Simucube manufacturer:

    Elecrically, a potentiometer looks like this (note that SimuCUBE uses 3.3V, but this can be ignored if you just follow the wiring example and connect to the 3.3V pin).

    and a button can be wired between the X12 pin 8 and any other pin on X12.

    But I don't think you want to send back 5V to the sim cube ...

    Do not connect 5V to simucube.
    After the manufacturer gave me that instruction corrected me today and told me not to connect it to 5V

    I'll delete the whole post.

    Wait, you just need to do a divider with two resistor ?

    Maybe with an AOP follower at the end of the potentiometer ?

    Manufacturer reply:
    Arduino's and Bodnar circuits use 5 V microcontroller, where as the STM32F407 on SimuCUBE operates at 3.3 V. That is the main reason.

    You can try to use that sensor you linked. Most of these sensors work correctly with slightly lower operating voltage.

    What do they advise?
    To connect a pedal and keypad use the Simucube or use Leo Bodnar
