I just tried it and it works. Instead of the ledpin 2, I used LED_BUILTIN to make things easier. In this case, no need for "int ledpin=2; // D4 in ModeMcu"
Hello there, This project does not use internet. It works over the local network. So how can I control the nodemcu with an html page on my webserver. Pls help me.
I want to control 2 sets of grow lights I have and I'm trying to see how folks do it. This was very informative and nudged me closer in the right direction so thank you for this! For the folks wondering how you can control this from anywhere in the world: your router has a public facing IP address, for example's sake let's say: 52.230.196.72 On this router, you go to some setting generally meant for port forwarding and say you want to open port X (say, 7777) [host] you would also say any request sent to that port will be forwarded to say port 80/443 at 192.168.0.100 [forward host] From the outside world, a request sent to 52.230.196.72:7777 would be forwarded to your internal host of 192.168.0.100:80/443. Of course, security and whatnot so I'd be careful - but port forwarding is very useful. A quick project if you'd like some insight without the risk of opening your network to the world, grab a free download of virtualbox and setup a VM with any linux distro - then right click on it in the menu, go Settings > Network > Advanced > Port Forwarding. Pick any non-conflicting number for your Host Port, and pick 22 for your Guest Port. After your linux guest is setup and ssh is enabled, from the host run: $ ssh -p [host port] [username]@localhost this will establish an ssh tunnel between your main system and your virtual machine so you don't actually need the interface up to work with it. You could also connect to it from any other device on the same network with ssh capability by pointing at your ip address rather than localhost. Once you've done it you realize how easy it is to do the same actions on a router. Or you could have your router point to your host to point to your vm, and on and on.
When I am using a 5v relay connected with nodemcu , although the relay module turns off and on but relay clicking is not happening and when I am powering it from a different source and only connecting the data input pin of relay to node mcu , the relay does not turn on at all
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
Hello sir your video is nice But I am having a doubt regarding website appearance can we add some more features on website like pictures and scrolling text
This is local IP control - not through INTERNET. Still its possible following below steps. 1. Get Static IP from your ISP provider 2. Do setting at your Wifi router to NAT and route to local IP running in NODEMCU. This way you can control the bulb anywhere from world.
Hey brother really inspired by your video.. I jus need a help.. I have made the circuit.. Wen i turn on using blynk.. The led on d relay lights up but when a bulb is connected it doesn't glow and my relay doesn't do any click sound.. Plz help.. M jus a 12 year boy.. N i have assured my parents to make this n if i be successful they ll give me more components please help
@@r.vigneshvignesh9654 Its very simple,Port forwarding is completely depends on your WiFi Router type,You can find lots tutorials for that..Still if you face any issues let me know
if (request.indexOf(" /LED=OFF")! = -1) -- Sir how to resolve this error if it really an error, then why it not found in just above code which is similar to it.
I am using 4 channel relay.... But that needs 5v but in node mcu 3.3 v is only available....so please help me... How to give the relay external power supply
Buy a cheap SMPS adapter which gives you a 5V supply. Apart from this, you can also use a FTDI board or simply a dual (3.3V and 5V) output board. More reference...ua-cam.com/video/f12FB0FDZkk/v-deo.html
Hey, Please do not use "having" like you are now and simply say "has" as that is correct. having is used only as a verb as in "i'm having lunch". hope this helps make your videos better.

where s the final code?
nice video clear presentation easy to understand superb
Good explanation. in future please use camera stand for better video performance
thanks brother...this video will be very useful to all beginners. i checked this code with node mcu and relay
Great video, clearly explained 👍👍
So nice
Indian Servers University rockzzzz
It not controlling from internet. It is your local home wifi network!
you can try to port forward ;)
you are right
LQ but very detailed. Kudos!
Thank you so much. You make me understand the Basic.
How this will work if we want to do the same from all over the world?
Use public ip or ngrok service
Hello there,
This project does not use internet. It works over the local network. So how can I control the nodemcu with an html page on my webserver.
Pls help me.
Very Nice Explanation
Very simple to understand, i tried other boards without success, nodemcu can be connected directly to pc and not need for Serial data transfer
where is the code link
Thank u brother for such a good video
Excellent

That's absolute...
according to video you made it is a local server please make one video how to host that server using some mobile network or a home wireless network
You can use no-ip service or use public ip instead of Lan ip

i am try to built a home automation project.
Thank you very much. Please help me
You can use Vin pin of node mcu to get 5v output , connect this 5 volt to power up relay
hey, i want to ask something, can i use portable modem device instead of Wi-fi router for the local network connection?
4:06 "..after openin' that lil' bitch.." :D tanks for the video
you are controlling it just from your home wifi once you out of that wifi range or even u use any other internet connection you can't control it..
Hey after opening the serial monitor there are only some symbols showing up and none of the available wifi networks are showing up there
i need documentation for this project pls can anyone help me out? thanks in advance
sir please help? how many codes you inserted in 1 wifi module? it detect all 3 codes?? it doesn't reset after uploading 1 code?
Hello sir your video is nice
But I am having a doubt regarding website appearance can we add some more features on website like pictures and scrolling text
Hello, what a great video! But I can't find the link to download the code. Can you send me, please?
Uhu its only wifi conteolled my dear.. please do as you talking. Its not controlled via global internet.🤔
This is local IP control - not through INTERNET. Still its possible following below steps.
1. Get Static IP from your ISP provider

how many relays we can connect with a nodemcu at the sametime ?
Dear Friends what should I do to access this wifi from anywhere without blink or any another third party applictaion
this code is through the LAN not on the internet, if you disconnect the internet it will work correctly.
can we use rpi instead of Arduino
I typed the ip address in url. remote is not coming. it's showing" site can't be reached". please help me.

How to Control this bulb over internet?
( that web page can be viewed over internet??)
Sir how to use the eeprom to store the pin state for on or off. If the light cutoff at that condition.
How can i add a Button (One way) to this same? Any video for that?
You are using home network to control the bulb not the internet.
This only control from same wifi network connected devices, you can't control this anywhere in the world....
Helo ratul raat by using port forwarding method we can control from anywhere..
Using blynk server

Does the board can execute the sketch if it s unplugged form the pc an plugged with a dc adapter ?
No
Relay buy link please? Or wts the name of tat relay
where can i find the code for this?
sir.. where is the link.. u said..
Can we use ardino here
Sir I can't see the esp8266 option. I'll tried so many times please help
Please make a video with 4ch relay, OLED display and node mcu
Where can i buy node mcu
If node MCU is rest pressed or supply to node MCU all the output pin is high
Output of the node mcu is 3.3 volts right....so how could it operate a 5 volt relay
The VU output of the Nodemcu is strong enough to power a 5v relay and the pins are strong enough to give the signal. I was surprised too, but it works
agar reply na de sako to phir kyu video banate ho!
Great , but this is not over internet controlling .
I want a budget details. how much cost for this project.
make a list of parts and then do some research...amazon, ebay, etc
connection disgram pls, including relay and nodemcu power input. i guess nodemcu work with 3.3 v only
Ctrl shift M
I am using 4 channel relay.... But that needs 5v but in node mcu 3.3 v is only available....so please help me... How to give the relay external power supply

You can give 5 -10 V to NodeMCU. There is pin as Vin
you can use arduino uno board
Deepanshu Kumar don't you think spending 900 rupees just to get a 5V supply is expensive!
Simple give the vcc from lm 7805 voltage regulator
HOW I CONNECT PUBLIC IP OR INTERNET... PLZ........
awsm 👌👌
sir you can give me this project coding and diagram plzz???
perfect
please provide the code in description
Magic!!
in scanning session the nodemcu esp8266 wifi network was not shown and disabled what can i do for enabling the wifi network
Sandeep nani change the baud from 9600 to 115200 in serial monitor
worked for me thanks alot
is there is no wifi what is the problem
where is the code link to control the light
you are not controlling from internet, the ip is your local network ip.
Its a local hoist application not remote host web server
