Dear @Mus_Sopee,
If you have doubts regarding those codes…start using the “search” function in this site, you will find several examples about your project that will help you as example:

(SOLVED) Looking to control a servo motor with slider

As I stated before, we are not here to write your code for you… you will need to learn how to code for Blynk on your own, but we will help with specific issues as you learn. For example, controlling a servo motor from a slider is very easy… BLYNK_WRITE(Vx) // Slider set to Vx and to range 0-180 { int SrvoPos = param.asInt(); // get slider value Servo1.write(SrvoPos); // move servo to value } But not sure what you mean by automatic mode… you want the servo to just keep moving back and fort…
