My Servo motor goes 0 to 90 to180 degree counter-clockwise is there anyway to make it clockwise?? Like If I do `myservo.write(90);` I want it to go 90 degree to the clockwise direction NOT counter-clockwise. I can use ESP32 if required.

Can you be more specific about "My servo motor"? What model? A link might help.

The direction of movement will depend on where it started. Does the servo start at zero or 180? 90 should be right in the middle.

Yah you are right but I am fixing this servo (_Screwing on board or something_) and if it goes in other direction things might get damaged, so while fixing I'm keeping it 0 degree (because **I think** when on boot servos tends to go 0 degree) so when `myservo.write(90)` I want it to go 90 but in clockwise, by default it goes counter-clockwise to 90 degree. **Or** I fix it on 90 degree and write 0 to move 90 degree clockwise??

Start at 0 and go 90, it rotates one direction.  
Start at 180 and go to 90, it rotates the other direction.  
Sounds like you need to boot the servo to 90. Now it can go clockwise or counter-clockwise.

No there's no code right now I'm just looking for a way to go servo in clockwise direction if its start from 0 degree (by these I mean the potentiometer is in 0 degree position like I keep it on 0 with the help of `myservo.write(0)` then screw it on board), but I think I have to screw it on 90 degree `myservo.write(90)` to move it to 0 degree `myservo.write(0)` (90 degree clockwise direction) .

Start at 0 and the servo will move in only one direction.  
Start at 180 and the servo will move in only the other direction.  
Start at 90, and now it can move to 0 or 180.

Simply position at 180-angle, 90° position stays same, you are only swapping 0° and 180°

What device is sending the signal to the servo then? Repeating the same story doesn't help.

It goes from 0 to 180 degree (Counter Clockwise direction) then comes back to 0 degree (Clockwise direction), but I want to change the direction, like I want to make it go 0 to 180 in clockwise direction.

As said instead of writeing:

`myservo.write(pos);`

write:

`myservo.write(180-pos);`

Really?? If `pos = 90` and current position is 0 degree does it will not go counter-clockwise (default direction) to 90 degree as `180-90 = 90`? And yes I have tried, it goes counter-clockwise to 90 degree which I don't want.

First I executed (to go 0 degree position):

```arduino
#include <ESP32Servo.h>

Servo myServo; // Create a Servo object

// Define the pin for the servo signal
const int servoPin = 27;  

int pos = 0;

void setup() {
  myServo.attach(servoPin);  
}

void loop() {
  // Move servo to 0 degrees
  myServo.write(pos);

}

```

Then this: (Result is same as with `myservo.write(pos);`)

```arduino
#include <ESP32Servo.h>

Servo myServo; // Create a Servo object

// Define the pin for the servo signal
const int servoPin = 27;

int pos = 90;

void setup() {
  myServo.attach(servoPin); 
}

void loop() {
  myServo.write(180 - pos);

}

```

Woah. Different approach may be needed. See if the following description fits:

When I mount my Servo, I want to know what position (0...180) it is set at so that when it powers up it is centered. My code will assume it is centered, so it could move either direction after that. If it starts at 0 (or 180), there could be damage done when the code starts.

IF that's the case, write a short code in setup that sets the servo to 90; put nothing in loop(). Upload that code. When it runs, the servo will move to 90. Now power it down - the servo should not change position.

Now, write your main code. MAKE DARN SURE you set the servo position to 90 in your code BEFORE you servo.attach(pin). That is the point in time when the servo code begins to control the position, so your code will start at 90.

Does that help?
