Many people are asking questions about how to use its GPIO pins. Which GPIO pin can be used as a digital input-output pin? Which GPIO pin can be used as an analog pin? And which pin should not be used to use thi
这些是可用作 ADC 和相应通道的 GPIO: ADC1_CH0 (GPIO 36) ADC1_CH1 (GPIO 37) ADC1_CH2 (GPIO 38) ADC1_CH3 (GPIO 39) ADC1_CH4 (GPIO 32) ADC1_CH5 (GPIO 33) ADC1_CH6 (GPIO 34) ADC1_CH7 (GPIO 35) ADC2_CH0 (GPIO 4) ADC2_CH1 (GPIO 0) ADC2_CH2 (GPIO 2) ADC2_CH3 (...

The ESP32 has 34 GPIO pins in total numbered GPIO0 to GPIO39. Some GPIO pins are not accessible to users because they serve a special function. Examples of these are GPIO20 and GPIO28 to GPIO31. Moreover, GPIO37 and GPIO38 are not accessible on the development board. Also, take note...

In this tutorial, we will learn how to use GPIO pins of the ESP32 devkit with LED blinking examples using Arduino IDE. Whenever any beginner starts learning about any microcontroller-based development board, Experts always recommend beginners to start with an LED blinking example which is also kn...
