#include <Servo.h>

Servo joint;
const byte servoPin = 11;
int angle = 0;
int delta = 2;

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

void loop() {
  joint.write(angle);
  angle += delta;
  if (angle <= 0 || angle >= 180) {
    delta = -delta;
  }
  delay(15);
}

How it works

Move a hobby servo smoothly across its angle range.

1. Connect servo signal to servoPin.
2. Power the servo from a suitable supply and share GND.
3. Attach the Servo object to the pin.
4. Write a new angle every loop.
