Control Multiple Servo motors using ESP32: Multiple Servo ESP-SERV3
Control Multiple Servo motors using ESP32: Multiple Servo ESP-SERV3
This video shows how to control position of Multiple 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 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 https://dl.espressif.com/dl/package_esp32_index.json Watch video for instructions.
