// Refactor the LED fading code to control the position of a servo motor connected to a pin using PWM.
// Implement functions to move the servo motor smoothly from its minimum position to its maximum
// position and back again over a specified duration. Assume access to PWM functions in your library.
// You can rotate the servo motor shaft from 0𝑜 to 180𝑜 by varying the PWM pulse width from 1 ms to
// 2 ms for a 50 Hz (20 ms period) signal. This corresponds to a 5-10% duty cycle on a 50 Hz waveform.
