Google firebase based home automation using NodeMCU (PART1 & PART2)

#nodemcu #projectideas #schoolproject #college #finalyearprojects
Google Firebase Database based 4 Channel Relay Control(IoT Project)
This project is all about how to control a relay using the google firebase database and Android app. How to make an android app using MIT App Inventor(STEP by STEP).
so that you can make some awesome Projects like:
#1. Google Firebase-based Home Automation.
#2. Controlling robots over the Internet.
#3. Controlling AC voltage over the Internet.
#4. and many more projects like this which you want to
control over the internet
So this tutorial is having three parts.
PART 1: Setting Google Firebase Database.
PART 2: Android App Making using MIT App Inventor(STEP by STEP).
PART 3: Hardware Section.
Hardware Requirements:
# Node MCU.
# 4 Channel Relay.
# 5v Supply.
This Video covers PART 1 and PART 2 in which We will learn
# How to set up the Google Firebase database for the Android App.
# How to make Android App using MIT App Inventor(STEP by STEP)

How it works:
Whenever we click a button on the Android app, the App will update the variable value in the firebase database. And in the hardware side, NodeMCU will be checking the variable value of the firebase database. Whenever the Node MCU gets the variable value of "1" it triggers the relay to turn ON by providing a LOW voltage at the Arduino PIN and whenever it finds the variable value as "0" it
triggers the relay to turn OFF by providing a HIGH voltage(5v)
value at the Arduino PIN.

Salute to you bro ❤️, i just have one question, how to make multiscreen app and upon clicking the button on screen 1 the app switch to screen 2 can you please tell me how? I need to submit my project till 20 june, this video saved me but i now want to make my application more fancy

[sadiqueimam]

Firebase and nodemcu communicates fine for a while but after few minutes nodemcu stop responding. Can you help me with this?

[ivanyacobrepi]

Iam using esp8266 2.4.2 version and arduinojson 5.13.5 and then driver ch341SER. Why your project can't run? Please help

[kashishnaqvi]

Hey, Is there any way we can build an app with MIT app inventor for different nodemcu boards, as we always have to add the firebase token and url in Firedatabase properties, we always have to edit it then compile the project, Can you please tell me if i can fill the token and url of firebase from outside the code for multiple boards? Please help, it is urgent.

i tried but found error in compiling
im pasting it in comment .. please check and help

el secreto de la base de datos está obsoleto, ahora cual es la alternativa, ahí en tu video se ve perfectamente que dice que está obsoleto.

sir i make this... it's work well

[pawansinghrajput]

I have made the project with 8 screen but when i press on/Off when i am on the screen its work but when i switch the screen to another it again show normal no on/Off button visible which i have pressed

[vatanz]

hello. nice project. just one problem I run into is that when the nodemcu is reset it sets the value in db as O to all of the FB's. How can change code to get the status before the reset. eg. Lamp was ON, after reset it should stay ON not OFF. Looking forward to your help.
