Google firebase and NodeMCU Relay Control (PART3)

Google firebase and NodeMCU Relay Control (PART3)

Google Firebase Database based 4 Channel Relay Control(IOT Project)
This project is all about how to control relay using google firebase
database and Android app. How to make android app using MIT App Inventor(STEP by STEP) in PART 1 & PART 2 video. Link is given below.
so that you can Make some awesome Projects like:
#1. Google Firebase based Home Automation.
#2. Controlling robot over Internet.
#3. Controlling AC voltage over Internet.
#4. and many more projects like this which you want to
control over 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 3 in which We will learn
# Circuit making, Code Explanation
# Project building and testing

PART1 & PART2 video link: https://www.youtube.com/watch?v=Wv8-lRN_7dU

How it works:
When ever we click a button on Android app, the App will update the variable value in the firebase database. And in the hardware side Node MCU will be checking the variable value of firebase
database. When ever the Node MCU get the variable value as “1” it triggers the relay to turn ON by providing a LOW voltage at the Arduino PIN and when ever 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.
