I guess with calibrate you mean that you want to use for example 0 - 0.5 from the range of 0 - 1, and that this 0.5 has to become 1.

That's just simple mathematics: 1 / 0.5 * adc_value
Or the same result: 2 * adc_value

Thx now I have a range of 90degrees of the potentiometer starting from the one end.
Another question and thx again.
To move the 0 from potentiometer let's say about 30 degrees?

That's again just mathematics :)
Have a good look at the previous one, and you should be able to solve it.

Hello
My throttles are working super fine thanks to you.

And last ❓ this is the cherry on the cake
For ZIBO motorized throttle
I want to use servos from R/C
To activate the servo I need AT in state on+ N1 or SPEED or LEVEL CHANGE in state 1.
THIS IS THE BIG QUESTION FOR ME
ANYWAY THANKS AGAIN

I believe that @Keith Baxter was working on something like this?
