ESP32 Servo Motor (Potentiometer Control)

In this project, we control an SG90 servo motor using a potentiometer. We adjust the servo angle by mapping the analog value read from the potentiometer to the 0–180-degree range. Thanks to the ESP32Servo library, any GPIO pin on the ESP32 can generate a PWM signal. This is a fundamental control method for robotic arms, camera gimbals, and automatic door mechanisms.
