Add a attribute for the maximum angle for a servo motor.

[Koepel]

It was mentioned in the Discord channel that the servo motor can only do 0...180 degrees.

Could a attribute be added to change the maximum angle?

Well known webshops have often servo motors for special situations with other angles. I see them from as low as 0...90 degrees up to 0...360 degrees (not continuous).
From what I read, the same pwm signal results into the full swing for that servo motor.

The limitation of 0..90 you can do via software.
Encapsulate the function that controls the servo, passing the angle and limiting the angle.

You can use the Arduino constrain function.

void setAngle(int angle){ 
  int pos = constrain(angle, 0, 90);  // limits values ​​between 0 and 90
  myservo.write(pos);
} 

or complete:

#include <Servo.h>

Servo myservo;  // create servo object to control a servo
// twelve servo objects can be created on most boards

int pos = 0;    // variable to store the servo position

void setAngle(int angle){ 
  int newPos = constrain(angle, 0, 90);  // limits values ​​between 0 and 90
  myservo.write(newPos);
} 

void setup() {
  myservo.attach(9);  // attaches the servo on pin 9 to the servo object
}

void loop() {
  for (pos = 0; pos <= 180; pos += 1) { // goes from 0 degrees to 180 degrees
    // in steps of 1 degree
    setAngle(pos);                // tell servo to go to position in variable 'pos'
    delay(15);                    // waits 15ms for the servo to reach the position
  }
  for (pos = 180; pos >= 0; pos -= 1) { // goes from 180 degrees to 0 degrees
    setAngle(pos);                // tell servo to go to position in variable 'pos'
    delay(15);                    // waits 15ms for the servo to reach the position
  }
}
