Hi everyone!
I'm planning to control the launch control RPM with a pontentiometer to anytrim input. I wonder what's better for the job:
This is with a simple 10K linear potentiometer:

Or with a voltage divider, wich looks like this:

How you guys used to do that?
Anybody? Nobody did the adjustable launch control? ???
that's not the way you do it :)
I mean, why there is a pushbutton?

Because i want to activate it on the same circuit. In this way it's only need 1 analog input. When i wire the button to another input, then the launch control will be using 2.
So if i push the button -> launch control activated to the adjusted RPM (which i can adjust with the potentiometer).
If i release the button -> launch control deactivated.
Sooooooo? Nobody? Really? ???
I'm not so sure that both of these functions can use the same input. Enable and adjust at the same time. Maybe it will work?
Personally, I'd try it with the first diagram, as the voltage divider will just make the control less granular. That may be an advantage at the end, but try without the voltage divider first.
I see the 2 diagrams as voltage dividers with about the same scale(0-5V or 0-4.9V) but I may have missed something.

Thanks for the reply! I guess i will do it on the separate way then. I thought it will work on one input that way, don't wanna experiment with.
