Ready to control your robot project with motors, servos, LEDs and more using a game controller paired to an ESP32? Not only will I show you how to wire each of these components to your ESP32, but also how to power servos and DC motors the right way.
Then we'll move on to the Arduino code, where we'll use the Bluepad32 library to make pairing your game controller to the ESP32 as easy as uploading the code and pushing your "pair" button. After that, I'll show you exactly how to use code blocks to assign the actions of each component in your robot project to a button press or joystick movement on your game controller.
In this ESP32 + Game Controller Tutorial:
▶︎ How to wire components like LEDs, servos and DC motors to an ESP32
▶︎ How to provide external power to current-hungry components like servos and motors
▶︎ How to get the values to identify every button and joystick on your game controller
▶︎ How to write Arduino code for each button and joystick on your gamepad to control speed and direction of DC motors, servo positions and turn on LEDs
This ESP32 project builds on a previous tutorial where we learned how to pair a game controller to an ESP32 using the Bluepad32 library:
