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. The ESP32Servo library generates servo signals on suitable output-capable GPIO pins of the ESP32; this project uses GPIO 18. This is a fundamental control method for robotic arms, camera gimbals, and automatic door mechanisms.
