ESP8266 Digital Input and Output with Arduino IDE – GPIO Pins

ESP8266 NodeMCU digital input output led and push button arduino ide

In this tutorial, we will learn how to use GPIO pins of ESP8266 NodeMCU module as output pins as well as input pins. Accordingly, we will also show how to interface an LED controlled via a push button with the ESP8266 board. We will be reading the value from the Push Button and lighting up … Read more
