[FEATURE REQUEST] Support for RC-Servo operated valves
I realize that stepper motor is in the todo list, but I stll want to lift the posibilty to use RC-servos to controll valves.
Yes and there are loads of code hints for esp32 as well as Arduino in general. https://en.wikipedia.org/wiki/Servo_control
PWM is pretty trivial to implement but it will require additions electronics as I suspect that the servomotor will exceed the capabilities of standard output current capacity (nominal 500mA). This is easy enough to do using a mosFET. The new PCB also now has a prototype area where additional electronics like this can be added which includes direct access to molex pins.
I suspect that we will also use the same philosophy for PWM based IAT bypass valve to fine control the bleed pressure
RC servos typicaly rus on 3.6-5V and only require puls signals, pusl length controlls direction and travel.

The PWM implementation will also be useful for motor control as discussed in #186 Good for DIYFB V3
