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

Project Video
Project Details

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

  • code ESP-SERV1 Using ESP32 to Control Servo motor to move it 0° to 180° or in reverse or any angle
  • code ESP-SERV2 Using ESP32 to Control Servo motor with Potentiometer to move it 0° to 180° or in reverse or any angle
  • code ESP-SERV3 Using ESP32 to Control Multiple Servo motors to move them 0° to 180° or in reverse or any angle

The link to use in the "preferences" of Arduino IDE for ESP32 board Watch video for instructions.

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