Fundamentals of ESP32 Peripheral Control: Detailed GPIO Applications and Input/Output Examples

1. What is GPIO? GPIO (General Purpose Input Output) refers to “general-purpose input/output ports,” which are pins that can be flexibly configured as input or output through software. Typical applications in embedded development include: Controlling output devices such as LED lights, relays, and buzzers Detecting input devices such as buttons and dip switches Interacting with … Read more
