Controlling Servo motors with ESP32 for robotics | Beginner tutorial
In this video we learn how to control servo motors using the ESP32, starting from the basics and gradually building more advanced control methods.
We begin with a single servo motor, then expand to multiple servos, control a servo using a potentiometer, and finally use an I2C servo driver to control many servos from the ESP32.
To finish the project, we build a WiFi web interface that allows the servos to be controlled from a phone or computer using simple sliders.
This tutorial covers several important concepts including PWM control, ESP32 servo libraries, power considerations, and scalable servo control using the PCA9685 driver.
By the end of the video you will be able to build projects such as robot arms, pan tilt camera mounts, animatronics, and other robotics systems using servo motors.
