ESP32 Interface with GPIO Expander PCF8574 || Pin extender use with esp32
Показать описание
In this video, we will guide you through the process of interfacing the ESP32 with the PCF8574 GPIO Expander. The PCF8574 is a handy I2C device that allows you to expand the number of GPIO pins on your ESP32, making it perfect for projects requiring multiple inputs and outputs. We'll cover the hardware setup, necessary libraries, and provide detailed code examples to help you get started. By the end of this tutorial, you'll be able to control multiple devices using the expanded GPIO pins on your ESP32. Don't forget to like, subscribe, and hit the bell icon for more tutorials!
