/*
In this example an additional functionality is used.

AiEsp32RotaryEncoderNumberSelector is that additional helper which will hide calculation for a rotary encoder.

In example 1 - you can select some temperature between -12 and +31.5 degrees in steps by 0.5 degrees; using precision of 1 decimal
In example 2 - you can select some frequency between 6999000 and 7000000 Hz in steps by 10 Hz; using precision of 0 decimal (integer)

Internally AiEsp32RotaryEncoderNumberSelector will do the math and set the most apropriate acceleration, min and max values for you

use setRange to set parameters
use setValue for a default/initial value
and finally read the value with getValue

So, this value is actually value you need

In code below comment / uncomment example 1 or 2
