i have this code, i'm try to understand where i need to config the serve move 90 degrees
and then Whenever I want again he'll turn back again 90 degrees
Thanks!!

myservo.write(val);
}
Move servo to 90 = myservo.write(90)
Move back to 0 = myservo.write(0).
Where you put those commands depends on when you want them to happen and how you're going to tell the Arduino when you want them to happen. "Whenever I want" sounds like you're going press a switch or send a command or something but you haven't given any details.
i'm try to understand where i need to add to the servo to move 90 degrees.
on command will move 90 degrees and stop, off command will turn back again 90 degrees.
Thanks for try to help me.

Writing to the servo is in the callback function where varaiable 'state' seems to be true for ON, false for OFF. So try this and see if it does what you are looking for:
if (state)
{
// int newVal = beginVal+15;
// myservo.write(newVal);
myservo.write(90);
resetMe=true;
Serial.println("ok");
} else{
// myservo.write(beginVal);
myservo.write(0);
}
If that's not what you meant try putting the original lines back but changing beginVal + 15 to beginVal + 90.
after i did whay you say the servo sopt spin.. and did not working.
with this down my servo now just spin and did not stop.
what i miss? i want with alexa on - servo will spin 90 degrees.
alexa off servo spin to 0 from 90 degrees

* fauxmoESP is a library for ESP8266-based devices that emulates a Belkin WeMo device
* and thus allows you to control them using this protocol, in particular from
* Alexa-powered devices like the Amazon Echo or the Dot.
*
* To activate a device or a gropu of devices, you should use voice commands, like:
* "Computer (or Alexa), turn on Light1" or "..., turn off Light1"
* "Computer (or Alexa), turn on Living Room" or "..., turn off Living Room"
* "Computer (or Alexa), turn on All Devices" or "..., turn off All Devices"

beginVal = myservo.read();This does not read the position of the servo, it returns the position that the servo was last commanded to move to. As at this point there servo has not been commanded to move what do you expect it to be ? My advice would be to set beginVal to a fixed value.
Incidentally, what type of servo are you using ?
my servo now just spin and did not stop.
It sounds like it may not be a servo at all. Is it by any chance a continuous rotation "servo" ?
i want the servo will unlock / lock my door.
i have all the part it make it, i just need help with the code.
how do i make it to look / unlock the door, the code i add did not working for me, what i miss it?
how can i make the servo to getting around like 10 sec One side to lock the door.
and again 10 sec to the other side to unlock the door.
Any help with the code will be Wonderful, appreciate your help.
If you are using a standard MG995 it can never "just spin and not stop". An MG995 will not turn more than about 140 degrees.
When you use the code from post #6 what exactly does the servo do? For ON. Then for OFF. Remember we can't see what's happening so you need to be very clear.
Also how is the servo powered? That is a fairly powerful servo and it MUST be powered separately from the Arduino.
I've been able to get what i need , now it turns 90 degrees as I should.
But how can i make it to turns back from 90 degrees ? Turn around to the other side, idea?
Thanks!

The latest version of fauxmo (3.1) has a variable for value which i believe can be set 0-100 designed for dimmers to my understanding but that could also be used in such a way that if a certain value is set then do so many degrees one way or the other depending on value spoken to alexa. I know this post is over a year old and the OP has not responded but if anyone was looking for a similar solution this gives the possability of 100 possitions or choices from one single device if you can remember what number corisponds to what command lol,
I cant even remember when to use an unsigned long or just a char its so difficult int it!
