IOT with Firebase: Control Led Using Firebase Console #Part2

by kavin sharma March 02, 2018

As we continue to learn IOT with Firebase using NodeMCU, we cover ON/OFF a LED connected to Arduino using Firebase Console .

I hope you find using Firebase with IOT to be a breeze after this tutorial. Please share your alternative problem solutions. All of the code and a transcript follows the video below.

If you like videos like this consider donating $1, or simply turn off AdBlocker. Either helps me to continue making tutorials

// FirebaseDemo_ESP8266 is a sample that demo the different functions
// of the FirebaseArduino API.

#include <ESP8266WiFi.h>
#include <FirebaseArduino.h>

// Set these to run example.
#define FIREBASE_HOST "esri-eea51.com"
#define FIREBASE_AUTH "qULRQbnuz-------------Q1FxHvM"
#define WIFI_SSID "kavin"
#define WIFI_PASSWORD "123456345"

void setup() {
Serial.begin(9600);
pinMode(D1, OUTPUT);
// connect to wifi.
WiFi.begin(WIFI_SSID, WIFI_PASSWORD);
Serial.print("connecting");
while (WiFi.status() != WL_CONNECTED) {
Serial.print(".");
delay(500);
}
Serial.println();
Serial.print("connected: ");
Serial.println(WiFi.localIP());

Firebase.begin(FIREBASE_HOST, FIREBASE_AUTH);
Firebase.set("LED_STATUS", 0);
}

int n = 0;

void loop() {
// get value
n = Firebase.getInt("LED_STATUS");
// handle error
if (n==1) {
Serial.println("LED ON");
digitalWrite(D1,HIGH);  
return;
delay(10);
}
else {
Serial.println("LED OFF");
digitalWrite(D1,LOW);  
return;

}
}

At last we are end up with great tutorial on IOT home automation using Firebase Console, NodeMCU
