- NodeMCU ESP8266 Wifi connect tutorial
This video we will connect the NodeMCU ESP8266 to the Wi-Fi router using SSID and password of our Home network Wi-Fi

Worked perfect, I have tried various others, this was the simplest, and I highly recommend. Even though I usually don't I decided to subscribe... good job! ( I did use a 220K resistor on the + of the LED just in case though)
Simplest sketch I've found, worked first time, really useful - thanks
Thank you. I recommend using a 400 ohm current limiting resistor on your LED.
Why 400 ohms specifically please?
@@jimpugh6357 I read that a GPIO on the ESP8266 can supply at most 12ma. So you need to make sure that any LEDs don't draw more than that. If you use a typical LED which has a voltage drop of 1.7v - this leaves you to insert a resistor in series which has a 3.3v (5-1.7) voltage across it. Using Ohms law (V/I = R) - Gives a value of 270 ohm (or greater) to limit the current to 12ma. So 400 ohm is a safe bet for these typical LED values.
@@johnwilson3918 thanks very much!
Thank you for your tutorial, you really helped me breakthrough to connect the esp8266 to my wifi AND eventually the blynk app. Thank you so much
Did you directly connect your convert to Arduino or PC?
Do you have idea about Esp8266 wifi module? I have a problem. AT Commands doesn't work. It only displays reversed "question marks". Thank you again
i need how can i make a single device for deuth with this because if you dont have connection to internet with this module they cant detect you without special devices and they can do it only when you attack so can i just conect lcd display and some switches to it or i need something like raspberry pi
Does it have any problem because mine is the dev kit v4?
ชอบมากครับ ขอบคุณครับ เห็นชื่อWiFiของคุณว่า สุขใจ เลยรู้กันครับว่าคงเป็นคนไทย ผมพึ่งเคยเจอคนไทยที่ชอบพวก Arduino ครับ ฮะโหล ฟรัม อเมริกา ครับ
what if i want to control a led matrix from my phone, i got it hooked up to a arduino uno but i want to be able to control the matrix from my phone, how would i do that?
Can this work on esp12f ? I have different shape board
Still can't connect to wifi. How the troubleshooting?
I have a doubt. Does this code work on esp8266-01?
Congrats engineers
Where do I get the libary #include from?
go to tools, library manager and look for ESP8266, download the libraby "by Community", then you should already have it included
@@Algo_de_Alguem What is the name of the library? I don't see any that say "by Community"
I'm getting hard resetting via reset pin .. what should I do?
Bhai ap MCU ki programming kis software se karte ho ...
Bro I m following ur videos.. it is so good...
I thought of doing a project using Arduino with 4 sensors n 4 servo motors...
But I need wifi connected with uno..
So can I use esp8266 for connecting 3 servo n 3 sensors
I have followed the exact code and connection. I have ESP8266EX chip. I am getting stuck at serial monitor showing 'Connecting......" Can't understand where I am going wrong. Also I am losing the blinking of NodeMCU once code is uploaded, which also is strange
i want to make wifi adapter using esp8266 as wifi adapter for pc .is it possible?
Perfect video for a beginner.
i had to use 9600 baud rate worked perfectly, thanks!
My esp8266 doestn detect any wi-fi. could it be broken? maybe
I am in 2022, And this sill Work. Awesome!
THANK YOU VERY MUCH. IT HELPED ME ..
Is there no need to connect a resistor between LED- and GND?
Just in case I think you should use it
Worked like a charm
Hey, wanna more videos related ESP-8266.
is that in one network??
I can't seem to get the "serial monitor" to read anything back... any adivce?
Thank you. It works great!!! A lot of thanks
Connected to the WiFi successfuly but led is not turning on
this is very useful thanks btw
I only get "Connecting to HW-BELTLINE-01" via COM console...
lovely development music in this video
Node MCU m bhi programming hoti h
HI Maker Tutor how do we contact you as we want to help you make more videos I can can send you Product to play with
Super super super super video sir thanks thanks thanks thanks thanks
Did you flash the code to Arduino or ESP ? Please reply.
Esp8266
1:05 that struggle
I use your code, there is no error but I can't be connected to the wifi. What should I do?
You're ugly
i have the same problem what is the solution
same problem
Works like a charm! thank you so much for making this :D
im getting an error about the esp8266wifi.h file not existing anything ideas about that?
@@jeanbastiendurand4897 u must have not conncted to to the right board
Hi it's very useful tutorial . I use your code , but still can not connected WiFi. And this is no error show.So what do need to check?
SAME PROBLEM.PLEASE HELP
in code you showed D13 but in practical you joined D7 confusion??????
it does not work: no error, but no connection. I am sorry to say that, but it looks like you never answer any comment.
make sure you go to tools, upload speed set to the highest
If you were trying to find very irritating "music" to aggravate viewers with you certainly succeeded.
Suggested Thanks.
Thankyou 👍
I got this error message:
Error: Request compile failed with message: 2 UNKNOWN: exit status 1
and
Error: Request upload failed with message: 2 UNKNOWN: exit status 1
most of the case the 115200 will not works with the node mcu NodeMCU ESP8266 :P
Sorry, it's no longer working. I tried to connect the same code to the same wifi router as I did before. The code works and is uploaded to the board. But it seems like it never connected to the wifi, only showing dots that never ends.
same here bro, help please
@@walidbinabdussalam5537 I had to update the Arduino ide or use 2.0 instead. It works, but there are problems with esp8266 such as an uploading error, it requires me to reinstall the driver every time I reboot my laptop. I prefer esp32 for my work these days, it's more stable and I never had problems with the driver
How many bars?
Can you show me how to take led off when wifi disconnected...?
Push reset button
@@prashantpandey2299 thanks..... :)
please help me, on my serial monitor only read ( connecting.......................................................................) and it isnt connected to WiFi
same here
same here
what about the driver?
If I want to disconnect it from computer and want to pass power from another normal source then how to do that?
You can power it from the pins!!!
@@Chris-mt9uy how
@@EpicGames-ep7bi With an external source power like a battery.
Just connect the + of battery in +5volt of esp and - of battery in ground of esp!!!!
@@Chris-mt9uy ok
WORKED....................
thanks, code is work.
thanks its very nice
Cool, but how can I change the SSID and Password of the wifi the board creates?
you don't change it through the nodeMCU, but through the router settings
Gulherme Pereira How?
You can change the code
hey I am mess up with my password can U help me to fix it up
Excuse me, but I recommend Googling "tutorial" vs "demonstration".
good work
thank you
hi! can you add a password to that, in a web page?
now i can understand
awesome
My Serial Monitor doesn't print the sentences properly (Wifi Connected Success!, NodeMCU IP Address ). instead, it shows a lot of weird characters (1384, room 16
tail 8
chksum Ȥl⸮⸮⸮CGH⸮yIi⸮⸮⸮ș⸮⸮⸮). Online people say it is the baud (something related to the speed 9600). I could not fix it :/
I have the same problem
@@bjornerikjohannsen7624 thx
Settings for example mail send copy paste ok
Worked!
ip not show how to fix
Programming kaisee Kare
working gud
Hi!!, for all those who get this kind of set of character on the serial monitor: ⸮⸮⸮CGH⸮yIi⸮⸮⸮ș⸮⸮⸮, here is the solution: github.com/esp8266/Arduino/issues/4005
If our wifi password changes then how will we configure ?
Upload code again with new password.
NO CONNECT
sketch_nov17a:1:25: error: ESP8266WiFi.h: No such file or directory

The music has blasted the commentary out completely cant hear a thing.
not working
Never worked.
let it be
He haw are u
This only connects to local wifi, not to the internet.
use
char ssid[] ="";
char pass[] ="";
don't use
const char* ssid="";
const char* password = "";
my serial monitor not working
Make sure 115200 baud rate is selected on the serial monitor
This explain absolutely nothing to me
change the music please
Как только вижу что ардуйня, сразу фигня
How cumbersome, troublesome!
I don’t like it!
thank you
I use your code, there is no error but I can't be connected to the wifi. What should I do?
Make sure u put ur wifi ssid and password in the code.
Divraj it’s working thank you so much for your response and for the video.
