NodeMCU8266 Digital Read (Push Button)

NodeMCU8266 Digital  input in serial Monitor  

Today i show you Digital read in nodemcu8266 module .

Digital read(Push Button)

A digital signal supplied to the NodeMCU8266  is known as digital input. This signal can be generated manually using a push button switch.

Push button switch is a switch which provides connectivity between its terminals when pressed. When the button is released terminals get disconnected.

First you hove to need Setup connection 

This is the code for NodeMcu on   Arduino IDE

void setup()


{


pinMode(16, INPUT);


Serial.begin(9600);


}


void loop()


{


if (0 == digitalRead(16)) {


Serial.println("SIGNAL HIGH");


}


if (1 == digitalRead(16)) {


Serial.println("SIGNAL LOW");


}


delay(1000);


}
