Is it possible to connect the mouse circuit to the steering wheel set motherboard instead of the potentiometer?

[denizari82]

The potentiometer cannot perform in games due to both the limited rotation angle and the serious gap, but most importantly, its response is very weak! When I try it with the mouse (for example, ETS game), the steering wheel in the game turns/reacts at the same rate and instantly even to the slightest movement. When I connect the mouse circuit to the potentiometer inputs of the steering circuit, naturally it does not work. I didn't get any results when I connected it to the other ends. I wonder how can I connect this mouse optic to the main board instead of the potentiometer or is this possible?

The mouse is not a potentiometer. It is most likely optical.

And without further information, like a schematic and a sketch of what you're trying to do, there's no way to answer you . (A picture of a board with some wires coming out if is useless.)

And what on earth is "the serious gap"??

The answer is: this is not possible.
Mouse is an incremental encoder producing 2D up/down counts, converted to x/y position by the HID USB interface. Potentiometer produces analog voltage, converted to position by an ADC.

You would need a device that translates mouse movement to analog voltage.

I guess the 4 four wires you try to connect present the mouse USB interface?

First of all, thank you for your answer and yes, the circuit with four wire outputs is a mouse circuit. I found something like this, I think that's what you're talking about, right: "Voltage Converter Module - Digital to Analog Signal PWM Adjustable Power Module":

That isn't suitable, it produces or relies upon a continuous PWM signal, what you need is something that converts the mouse USB signal into a variable resistance.

You need a device to interpret the motion of the mouse, which is in the form of "X-increasing", "X-decreasing", "Y-increasing" or "Y-decreasing" and by how much. I do not know of any commercial product that does this but it is a fairly trivial task to program a microprocessor to do it.

OK, thank you for your answer and help. As you said, it will be unnecessary to deal with this.
