Como puedo parar un servomotor de 360°

Need Help With My Project
#1

Hola, no sé como puedo hacer para que mi servomotor gire 2 segundos en sentido anti horario (botón V1) y luego pare, y que después apretando V2 gire en sentido horario 2 segundos y pare. Sólo puedo hacer que vaya de una dirección a otra, pero no hacer que se detenga. O bien que gire en direccion anti horaria apretando V1 y luego apretar V2 para que se detenga y que gire en sentido horario cuando presione V3.

A continuous rotation servo motor can be controlled by calling the servo.writeMicroseconds() function, which typically accepts values from 1000-2000. A value of 1000 should rotate the motor counter-clockwise at full speed. A value of 2000 should rotate the motor clockwise at full speed. A value of 1500 should cause the motor to stop rotating (and without any vibration). Intermediate values can be used to change the speed of the rotation.

// rotate counter-clockwise full-speed
servo.writeMicroseconds(1000);

// rotation stopped
servo.writeMicroseconds(1500);

// rotate clockwise full-speed
servo.writeMicroseconds(2000);

If necessary, you can fine-tune the values listed above based on testing with your actual servo motor. You could go as low as 700 or as high as 2300.
CAUTION: If you adjust the endpoint values too far (too low or too high), you might damage the motor.

If you need your servo to only rotate for a specific period of time, then simply use a blynk timeout timer (instead of delay function), something like this

servo.writeMicroseconds(2000); // rotate clockwise
timer.setTimeout(2000L, []() 
  {  
servo.writeMicroseconds(1500); // stop rotation
  });

thank you, very much. I’m gonna try it!
