Control Servo motor using Potentiometer and ESP32: Servo Pot. ESP-SERV2

This video shows how to control position of Servo Motor using Potentiometer and ESP32 Microcontroller to move it from 0° to 180° or from 180° to 0° or set your own values. You need to download the libary specifically work with ESP32 Arduino IDE/

We have 3 type of controling Servo Motor with ESP32

The link to use in the "preferences" of Arduino IDE for ESP32 board https://dl.espressif.com/dl/package_esp32_index.json Watch video for instructions.

 * This is Arduino code to control Servo motor with ESP32 boards.
 The position of servo is controlled by the position of Potentiometer (variable resistor)
