- In this IoT based project, we will learn how to do Home automation using NodeMCU and Blynk App. This is a simple but useful home automation project with Nodemcu and a relay module where we can control home appliances securely from the smartphone.
During the video, I have shared the circuit diagram, Arduino sketch, Blynk example library for this internet of things project.
Please check NEW Blynk + ESP8266 + IR + Sensor Project: • ESP8266 Project using ...
For complete project details (schematics + source code) visit ► easyelectronicsproject.com/es...
Download the Code: drive.google.com/uc?export=do...
**You have to install the Blynk library before uploading the sketch. I have shown all the details in the video.
Required components for this WiFi relay module:
1. NodeMCU board
2. Relay Module 5volt
3. 5 volt DC supply
In this video, I have shown step by step how to download and use the Blynk app for this smart house project. I have also shared NodeMCU pinout details, which help you to connect the 4-channel or 6-channel relay module with the esp8266 Nodemcu board.
After watching the complete video you can easily design this low-cost smart home device and control the relay module with wifi.

Which app to create thumbnail
Bro atleast you could have explained circuit 🙁
Bro relay ka volt kitna hai
hello there, mat i ask you a question sit? i try to use IoT pproject using nodemcu for my last project. But i have an issue that the nodemcu response is too slow after i give command from blynk app. Is strength of the internet connection influencing the nodemcu response? thankyou
can we use analog as an input and output, and at the same time we use a digital input and output?
or do we have to convert the analog signal into digital? Pls help me with this

hello after changing the token and my wifi network, I can't find the nodemcu board in the tools, but it must already be connected to the pc? or am I missing something?
First you have to download the esp8266 board. Then select NodeMCU 12E board.
@@TechStudyCell where should i download the card? I Havel followed all your step by step guide, i Have not seen this step
this is nicest project i really love it
How to put 5v from charger please explain
How many relays can we control using this code
Sir, Wi-Fi password is it Wi-Fi router,
Or Nodemcu has work as wifi.
Can you explain short what is said and it's password I am not understand.
Tq so much bro it works
Hlww sir we uploading a code perfectly but that wifi network is not showing
Please can you send the list of the components it's urjent
Is it ok if it's(Esp8266) Turn On all the day?I mean heating issues..
no issue
Great project.
But I'm getting a problem.
While compiling it says (esp8266. h no so file in directory) . And there are no ports also.
u Need to upload the Library and if the Port is not Showing Means U need to install the Driver..... there r two of Library is there one is CP2102 and CH340

Hello sir when I'm uploading it showing error
esptool.fatalerror.failed to connect to esp8266:timed out waiting for packet header
Pls solve my problem 🙏🏻
It port COM 7
It showing
The selected serial port does not exit or your board is not connected
But while uploading it blink blue led light in esp8266
Thank you bro👍
Welcome
In wait project RFID + relay + LCD ,tnks
Ok.. thanks for the idea
Sir this project must be use an a laptop
Hi, how do you power your ESP8266 board? What power supply do you use?
Mobile charger
@@TechStudyCell What voltage are you supplying to the board ? Is it 5V ? I can't power my 5V relay module even though I connect the relay with 5V input, how can you do that ?
You can also use step down transformer, Bridge rectifier, Capacitor, 7805 regulator to get +5v dc supply to nodemcu
Sir can you post the ppt for this project
Thanks for the tutorial. But you forgot to tell how to add board to arduino ide. Mine have a error while Uploading the sketch.
Btw with this project the light works only with blynk and not with the switch how to make it work with switch board button and blynk too?
Which board did you use for your project
Sir hum dunya k Kisi bhi Kona se relay control krsaktay han
Just like hum agar office m han or Pani ki motor on krni ha to office se on hojaye gi?
Yes. If the NodeMCU connected with the Office WiFi. Your mobile and NodeMCU are connected to Blynk server. So when press the button in Blynk app, it send the signal to Blynk server through the internet. And the NodeMCU received that signal from Blynk server.
PLEASE HELP .
CAN NOT FIND Board: "NodeMCU 1.0 (ESP-12EModule)" in tool
First you have to install the esp8266 board from tools board manager. Then select the NodeMCU
thank you very much
Welcome
amazing
Project cost ??
Very good project
Thanks
very good
thanks
Thanks
Thank you 👍👍
Thank you too
How to make blink app? Did you? Or already to use?
Download Blynk app from Google play store and please refer the video.
@@TechStudyCell oke thank you so much
Sir how through connect node mcu mobile hotspot or WiFi?
Just enter the hotspot name and password in the code.
What version of esp82666 you use sir??
NodeMCU 1.0 ESP12E
@@TechStudyCell i mean in the Arduino IDE
sir do we have to connect on same Wi-Fi or it will work on WAN
The app is meant to be controlled from anywhere in the world. Only issue is the new version of the app doesn't seem to have a NodeMCU device option.
@@zerobot_tech ok thanks
@@zerobot_tech can you suggest me which board should I buy
For both NodeMCU and ESP01 select ESP8266
Bro es ko google assistant sa connect kro
Super project 👍🏼
Question could you change me the code to 4 relays? 🤔
Please refer to this video: th-cam.com/video/O9VYZqWPNEQ/w-d-xo.html
It was showing led on relayboard but no sound in the relay??
same problem with me
I m also watching this thing because to triggering relay you have to give 5volt dc to relay
@@ameenurrehman5600 did you fixed that
Dogar 277 yes i fixed that
@@ameenurrehman5600 how did you fix that? Help please.
Nice IoT project 😊
Thanks
Thanks bro , please add the code in the description
Download the code from description. You have to install Blynk library as I have shown in the video.
@@TechStudyCell for esp8266 what version to install?
Nice
can i use esp32 instead of esp8266?

sir, what is a difference bitween ch340g and cp2102 esp8266? Can we use ch340g esp8266?
Awesome explanation.
I bought NodeMCU With 4-Channel Relay Board. In that 1 relay is soldered to D3 pin of ESP.
Could you explain how to use D3 pin as output? All other 3 relay is working as expected
Can u use this circuit manually also
