when their is no hope left you made my project so simple with your description....thank you sir...........................!
Good job. perfect video. congratulations.
Thank you very much AKV for creating such an informative tutorial.
Kindly confirm that it is essential to connect mobile and NodeMCU on same wifi connection or we can control through other city by using different wifi connector
We can control it by different devices.
Just go to project settings and at the bottom, press clone. You'll see a qr code.
Download the app in another device and log in with different account. And press the qr icon on the top. Then scan the QR code from your device. You'll have a copy of your project. And you'll be able to control with both devices.
Thanks
Can It be controlled from anywhere in the word, anytime?
@@prodyumnapal5430 Yes. Provided, you've configured everything correctly and are connected to the internet
Thanq very much for creating simple way to understand for beginners.....
So we will be needing a wifi router to that network we connect our node MCU board is that so ?
Nice work!!
Sir can it work on remote control also,or also from manual switch.
Sir mene ye relay jane bina relay khredli sir kiya ye relay hm kiya amplifier speaker protection ke liye laga sakte hei use kt sakhei k nhi ?pleas reply me
There are some steps missing. Like going to Preferences and adding the URL. Downloading ESP8266 Module from Boards Manager. Otherwise, everything else is in the Video.. Just created the COnnections and Configured Blynk App. Worked like a Charm! Thank you...
which url kindly explain
Akvtechnical.com
Can I use 8 or 16 channel relay instead of 4 channel relay on this setup? Pls reply
Sir plz explain about relay model wiring
Thanks man, how does Blynk works? in the last step
Bhai iske sath me touch sensor bhi laga sakte hai kya...
How to control my nodeMCU from anywhere?
Urs is working perfectly in local area only not from far places
connect it with a server and get a public ip through that you can on/off from anywhere
Can I connect my mobile and esp 8266 to two different n/w to operate it from anywhere in the world?
Hi sir,
what version you are using blynk iot?
Sir, if nodemcu is fitted in box then what to do so it will not be overheated
Thank you so much sir 💯😇😇😇❤️👍
How are you powering the nodemcu?
In the circuit diagram in ur website shows you've connected external 5 volts to vin pin of the board.
Can we use a simple USB cable to power it up instead?
Usb se power dene main aap ka board kharab hone ka khadsha h q k current phir zyada flow krega usse acha h app alag se power dedo
Hi
If we want to use it for single channel realy board production in quantity what are option to make app useable for our customers. It is not possible to program each device by different Authorization code.
Vcc on relay channel is 5v supply for node mcu?
Shall we control load with multiple phones ?
After connecting all the connections and dumping the codes in aurdino should i remove the usb cable and it is compalasary to give 5v dc supply
Yes, because u need to implement it in the real-world and not just keep it connected to the computer through usb cable.
And when it comes to providing power supply, a bulb or a LED doesn't glow without providing power supply. In the same way to run the Arduino and implement it in real-world application, u need to provide a 5V Supply to the board.
hi sir,
i can not install program to nodeMCU form my pc its showing some error.
please help me out , how to solve it
Will it work if mobile is connected to different wife and mcu to different wife
Yes you connect any wifi
How we can add blynk libery in arduino library?
Thanks for this video. It's working sir
Yes working
Can It be controlled from anywhere in the word, anytime?
If (WiFi.status () ! WL_CONNECTED)
Ye line void setup me likhna chahiye ya void loop me ?
Will nodemcu flashes after uploading program
Thanks sir aap ne ache se samjhaya
Welcome dear 😊
How did you connected that four bulbs
sir 4 relay kay sath location bhe add ho sakti
Ek hi samrtphone se hotspot Diya MCU ko aur usi smartphone se controll Kiya to chalega na sirji
Do you have the schematic or wiring diagram?
Bhai isme badi vali motor laga sakhte h kya
Let me know""" can we control two different mobile on this same project it possible?
Yes possible
bravo good job
Supr explanation
Ardeno is used here or not

Hello very nice job
Plz make one video for relay module wiring connect
Aap ache se samjhate hai please sir
teria como você postar o codigo por favor?
Hai bro
I did everything as you explained your video, but I am getting error while unloading code.error as follows
"Invalid library found in C:\users\habeeb\documents\arduino\libraries\sketch_feb29a:no headers files(h)
Like that and not working also
Please can help me to solve my problem
Thanks
nice guide
Sir we can control manually also this controller with adding 4 micro switch
You can control but I am not added in this project ok i will make one video for this ok
Can any one suggest if only one realy is working balance theee not..
Hi, I have a question. can i power up a 5 volt 4 channel relay module with a 5 volt 0.7-0.8 mAh wall type charger, which is basically use for charge the simple mobiles.
If yes, then how i connect, i mean what will be the circuit diagram. which wire will be connect with the vcc and which wire connect with the ground and which wire is connect with the ESP8286.
OR,
ESP8266 nodeMCU board 3.3volt is sufficient for 4 channel 5 volt relay?
i am try to built a home automation project.
Thank you very much. Please help me.
@@AKVTechnical is it safe to use external power supply
@@AKVTechnical can i use Vin pin of nodeMcu as input voltage of the 5v relay
@@DeViLsCrEaTiOn Vin pin is input positive voltage for board, It is not GPIO so you can't get output
man the blink library website which you have liked down in the description is not valid because it does not contain any file for the activation of blink library to perform any blink related project in the aurdino IDE
thanks bro i really wanted to ask the same question and i had the same problem please reply us
@@AKVTechnical thanks man
Is the node mcu reprogramable
Please Help, My Relay not Triggering with blynk buttons but relay led glow very dim almost invisible but when i connect relay input pin with nodemcu ground pin then its triggered, so please guide me what i have to do.
Please check voltage of relay module
@@AKVTechnical its 5v Relay
Are working properly but ek problem hai mano Main Light chali jati hai, or kuch der baad aati hai to sare realy automatically on ho jate hai, kuch aisa kar sakte hai ki light jane ke bad jab dobara light aati hai tab automatically realy on na ho realy tabhi on ho jab hum blynk app se button on kare. Please reply

Hello
kiya koi b android mobile use ho sakta hy??????
Jab nodemcu ko wifi se connect karna padta hai to iska matlb ham ise sirf wifi ke range me hi control kar sakte hai na?
Nahi wifi se nodmcu ko sirf internet de rahe ho aur ye duniya ke kisi bhi kone se oprate kar sakte hai
Node file not showing in a rduino file
Bhai agar hum 2 rooms mai alag alag mcu node use krte hai toh... Single phone se hum kese control karre... 2 rooms ko plz suggest
watch my latest video for that
Kya ye broadband se chalta h wifi
I dont understand the pins . Why you connecting the pins on D6 and D7 and in the code you write D0 D1 ? Doesnt matter which pins you select in the esp ?
It is circuit error I think, I write pin 0 and it is D3 in Wemos D1 Mini board
Bhai agar mobile say light on honay kay baad light chali jaye to kya light Anay Kay baad apnay app on ho jye gi please relp
Nahi iske liye sirf mcu me 5volt ki battery use karna hoga pur details ke liye Google per search karo (wifi home automation by akv technical)
