Help me too

I need help

I tried it. I think I want Servo to press the shutter to shoot or stop shooting.

How should I edit the source code?

Refer to the website

Add "#include <Servo.h>" at the top of the sketch.

Add a Servo object called, let's say "shutterRelease".

Attach the Servo object to an unused pin.
Initialise the position of the Servo object.

Operate the servo at an appropriate place.
Don't forget to return it to its start position.

And make sure you read the documentation about the Servo class's use of time resources

And don't forget to use code tags when posting code.

I'm not sure Will the servo recognize the rotation position like a stepper motor?.
When I press the button InOutSet.

No. RC servos are not steppers.

Is it important or significant?

AWOL:
No. RC servos are not steppers.

If I can't use Servo
Can I add a step motor?

Why can't you use a servo?

Yes, you can use a stepper if that's easier for you.

If you don't know what you want ....

It seems to me a job that would be a great deal easier to handle with a servo rather than a stepper motor.
