[EN] Arduino : ESP8266 GPIO
In this article, we will learn about GPIO (General Purpose I/O) or pin connect to an external device of microcontroller with C++ of Arduino using esp8266 as reference chip. This can be applied to Arduino Uno, Arduino Mega or STM32 as well. Under this article, we describe the duty of the pin, output and the input signal.
