Control Servo motor using ESP32: Single Servo ESP-SERV1

This video shows how to control position of Servo Motor using 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 that specifically works 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
