Getting hands-on with ESP32 GPIO pins and an overview of them

GPIO is a fundamental feature found in microcontrollers and other embedded systems. It refers to the ability of the microcontroller to interact with the external world by providing a flexible set of input and output pins. GPIO pins can be configured to either read or write digital signals, allowing the microcontroller to communicate with various devices and peripherals. As input, GPIO pins can detect the state of external sensors, switches, or digital signals. For example, we can read the temperature from temperature sensors. As outputs, they can drive LEDs, control motors, or interface with other electronic components. The versatility of GPIO pins makes them essential for a wide range of applications, enabling the microcontrollers to interact with and control the physical environment.

In this section, we will dive into ESP32 GPIO pins and explore their potential. By understanding this topic, you will be able to control...
