Writing the Code

Note

You can copy this code into Arduino IDE.
To install the library, use the Arduino Library Manager and search for Servo and install it.
Don’t forget to select the board(Arduino UNO R4 WIFI) and the correct port before clicking the Upload button.

#include <Servo.h>

const int servoPin = 9;  // Define the servo pin
int angle = 0;           // Initialize the angle variable to 0 degrees
Servo servo;             // Create a servo object

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

void loop() {
  // scan from 0 to 180 degrees
  for (angle = 0; angle < 180; angle++) {
    servo.write(angle);
    delay(15);
  }
  delay(1000);
  // now scan back from 180 to 0 degrees
  for (angle = 180; angle > 0; angle--) {
    servo.write(angle);
    delay(15);
  }
  delay(1000);
}
