Digital Input and Digital Output on the NodeMCU ESP8266

#ESP8266 #NodeMCU #ArduinoIDE #IOT
In our everyday life we turn ON and OFF numerous devices. Generally if we had to count it would be a big number ranging from 900~2000. Just count the number of times you have turned ON your phone screen and then turned it OFF.
Digital signals have 2 states : ON and OFF. These two states are going to be used on our ESP8266. So we are going to take digital input from a push button and give digital output from a LED as we start off with the ESP8266 NodeMCU.
You will have to set a GPIO pin to INPUT for the switch and another GPIO pin to OUTPUT for the LED. Remember that we are going to use the Arduino IDE.

[@martinnunez4163]

thank you very much i didnt know about the diference in the numbers printed on my esp8266 with the actual numbers i have to use in the program

[@praveenathsathyamoorthy495]

Will this work if giv external 5v supply to the board without the usb connection

[@ElectronicsSimplified7]

Yes ....
