twelve servo objects can be created on most boards Servo myservo // create servo object to control a servo Written by BARRAGAN and modified by Scott Fitzgerald Make sure you have the ESP32 board selected, and then, go to File > Examples > ServoESP32 > Simple Servo. Move the ESP32_Arduino_Servo_Library folder to your Arduino IDE installation libraries folderĪfter installing the library, go to your Arduino IDE.Rename your folder from ESP32-Arduino-Servo-Library-Master to ESP32_Arduino_Servo_Library.

The ESP32 Arduino Servo Library makes it easier to control a servo motor with your ESP32, using the Arduino IDE. Follow the next steps to install the library in your Arduino IDE: Installing the ESP32_Arduino_Servo_Library Mac and Linux instructions – ESP32 Board in Arduino IDEĪfter making sure you have the ESP32 add-on installed, you can continue this tutorial.Windows instructions – ESP32 Board in Arduino IDE.Follow one of the next tutorials to prepare your Arduino IDE to work with the ESP32, if you haven’t already. There’s an add-on for the Arduino IDE allows you to program the ESP32 using the Arduino IDE and its programming language. Or you can use a library to make this task much simpler. To control the motor you can simply use the PWM capabilities of the ESP32 by sending a 50Hz signal with the appropriate pulse width. This means that the PWM signal sent to the motor will determine the shaft’s position. Servos are controlled using a pulse width modulation (PWM) signal. You can position the servo’s shaft in various angles from 0 to 180º.

(This schematic uses the ESP32 DEVKIT V1 module version with 36 GPIOs – if you’re using another model, please check the pinout for the board you’re using.) How to Control a Servo Motor? So, you can follow the next schematic diagram to wire your servo motor. In our examples we’ll connect the signal wire to GPIO 13. Recommended reading: ESP32 Pinout Reference: Which GPIO pins should you use? Schematic

However, we don’t recommend using GPIOs 9, 10, and 11 that are connected to the integrated SPI flash and are not recommend for other uses. Note: in this case, you can use any ESP32 GPIO, because any GPIO is able to produce a PWM signal. If you’re using a small servo like the S0009, you need to connect: When using a small servo like the S0009 as shown in the figure below, you can power it directly from the ESP32.īut if you’re using more than one servo or other type, you’ll probably need to power up your servos using an external power supply. The power is usually red, the GND is black or brown, and the signal wire is usually yellow, orange, or white. Servo motors have three wires: power, ground, and signal. You can use the preceding links or go directly to /tools to find all the parts for your projects at the best price!

Micro Servo Motor – S0009 or Servo Motor – S0003.

This guide is available in video format (watch below) and in written format (continue reading).įor this tutorial we’ll use the following parts: Watch the Video Tutorial and Project Demo First, we’ll take a quick look on how to control a servo with the ESP32, and then we’ll build the web server. In this tutorial we’re going to show you how to build a web server with the ESP32 that controls the shaft’s position of a servo motor using a slider.
