- Arduino | LoLin NodeMCU V3 ESP8266 with Arduino | Getting Started | Connect to WiFi and Control the LED. In this project video i use LoLin NodeMCU V3 ESP8266 and Arduino IDE 1.8.9.
Download LoLin NodeMCU V3 ESP8266 Board for Arduino IDE (json arduino preferences) : arduino.esp8266... , or look at the Arduino code below, I added it there too.
Download Arduino Code here : drive.google.c...
If the code above doesn't work, try using the code on this web: enrique.latorre..., I copy it from there and do a little change.

if your serial keep writing ??>?
thank you
you saved my ass
@@blackpro5763 you welcome my friend
@@luisandresrodriguezgomez3343 you are welcome my friend
saved my life
It helped me . My LOLin can "breathe" now. Thanks! You've deserved your like.
Make sure to hold down the "flash" button when plugging the usb into your pc/mac. This will set it into "program mode". Maybe some are different.
Also, you have to unplug it again*Hold "reset" and plug it back in to actually run the code
Do you use the same NodeMCU as the one I used ? because at NodeMCU I don't need to do that.
@@utehstr Mine is identical but it may be a knock off. I got it on Ali and it does NOT say "Lolin" anywhere on it. However all other pins and printings are the same on the board. I know very litttle about the esp8266/Wemos/Nodemcu boards but i'm learning more each day. It is hard! hahaha. I found that, much like an esp-01, i had to hold the reset when plugging it in to make it run, as well as hold the flash when plugging in to program it. Thank you for the tutorial though!
@Josh You're welcome.
Thank you also for the information
Maybe this will help other people who have NodeMCU like you have :-)
Please share link to download "U S V" tool.
Nicely done. Easy to follow and does what I had hoped it would.
Thank you :-)
Please tell me which one is best mcu esp8266 V2 vs v3......?
i have NodeMCU V2, it's work for me on GPIO16 (D0), but when i uploaded sketch to my ESP i have this comunicat: Done uploading
Leaving...
Hard resseting via RTS pin...
it's normal comunicat or something is wrong?
I have never used NodeMCU V2 and I have never had a problem like that. After uploading does the code not work?
@@utehstr the code does work. I Just want to know why this comunicat pops up
@@bartekll7068 I don't know about this. Sorry can't help.
Some happens to me using v3, but it works, that's what matters i guess.
hi, Can I connect many sensors (2, 5, 10, 24...) into only one ESP8266 board ?
It worked really well, however when i use same wifi in my phone it's fine, but when i connect using mobile data it doesn't open url. How could i fix this. Let's say I want to have access while not being at home.
I have never tried that. Maybe you need a Public IP or online server. This will be my next project and if it's finished and successful I'll make the video. Sorry I can't help you for now.
If your devices are going to be on other networks you can access with ip address. (When your modem restarts you get new ip address. So you should get static ip address or you should get your new ip address to your phone. There are more than one solution.)
How come Blink needed a 262k upload to run the compiled code? And what libraries were used?
Thank you nice work
I have a question please
Can nodemcu work by using battery as power source instead of power from computer.
If that possible can you please tell my how to do it.
please
I am a subscriber for your channel from iraq.
Thank you for subscribing :-)
Of course NodeMCU can use batteries as a power source. I found a website that is good enough to explain it, see here : henrysbench.capnfatz.com/henrys-bench/arduino-projects-tips-and-more/powering-the-esp-12e-nodemcu-development -board /
Can you please make a video about using wemos ch340G connect with arduino and RFID and real time clock
sending the data to Google sheet .
Please
I can't make it for now, because I don't have wemos yet.
but, how do i add more commands to the page i get from the web browser. where, in the code does is this menu even derived from?
Any suggestions or examples of LoLin NodeMCU V3 ESP8266 with MQTT?

Hi . i tried to upload the 2nd coding to my board . However it seems that my ESP8266 are not able to connect with my mobile hotspot . Do u know how can i fix it ?
Hi. Make sure that the ssid and password you wrote in the Arduino code are correct. Also make sure that no other device is connected to your mobile hotspot if the mobile hotspot uses the setting to limit the number of connected devices.
esp8266 nodemcu v3 port is not visible, what should I do?
plz hlp
cannot convert 'uint32_t*' {aka 'unsigned int*'} to 'const time_t*' {aka 'const long long int*'}
Can we use same procedure for ecp 32?
ssid and password is our own connected hotspot right sir? because my code doesnt seem to give the supposed result in the serial monitor
Yes, and make sure your computer and nodemcu are on the same network.
@@utehstr What about connecting to it through the internet? Thanks
@@HushNinja You need to have a wifi network that you can connect your ESP to. If what you mean is that your computer is in a different one then you need to make your computer reachable from the internet. So you're gonna need a public IP adress (you most likely already have one but if you don't then maybe reach out to your ISP) and you're gonna need to configure your router to route incoming traffic on a given port to your computer. Also your ISP may have given you an IP address that changes, which you again would have to discuss with them, or use some DDNS service
Thanks you! of Buenos Aires
You're welcome 👍🙂
which libraries were used ?
Hello sir. Apabila saya upload command, akan keluar “the selected serial port serial.serialutil. SerialTimeOutException: Write timeout does not exist or your board is not connected” apa yang perlu saya lakukan?
Saya belum pernah mengalami itu, jadi maaf saya tidak bisa menjawab. Tapi mungkin link ini bisa membantu kamu github.com/esp8266/Arduino/issues/6110 , silahkan dilihat.
i had succesfuly made this one. is there away that broadband connection can be achieved ?
Sorry I don't understand what you mean, can you explain in more detail.

Do I need to install the driver CH340G which is written below the nodemcu??
Yes, if your computer has never installed the CH340G driver.
@@utehstr actually I have 2 node mcus.........One of LoLin and other one is Amica.......While connecting them the computer is able to read the Amica one but for the Lolin it says failed to install the driver........How should I proceed?
@@anirbandhar3424 I have never used Amica, does Amica also use CH340G ?
@@utehstr Amica uses a different driver but my PC is easily recognising that while only once it recognised Lolin after which the PC failed to do so
@@anirbandhar3424 Do you plug in Amica and Lolin on the same usb on the computer ?
I don't know, I usually don't go to RUclips to read long written explanations for things nor to listen to generic bop music.
I Can Only see Port USBSerial-3A20. Is this the right port to use?
Sorry I don't understand what you mean, can you explain in more detail.
@@utehstr After I installed Silicon Lab driver for Mac, I checked on Arduino software with my NodeMcu Lua ESP8266 CH340G ESP-12E board plugged in, I can only see 2 ports. One is /dev/cu.bluetooth-incoming-port. the second port that I can see is /dev/cu.usbserial-3A20. my question is was my driver installation done right? is that /dev/cu.usbserial-3A20 the right port to use with this board? thank you sir.
@@tangonovember4129 Sorry I have no knowledge of the NodeMCU Driver on Mac. Try asking this in the arduino forum.
@@utehstr It is Ok now. I used wrong driver. I supposed to use CH340G driver. Thank you anyway.

hi sir. sorry but where can i download the U S V ?? i don't know how . please :( I'm stuck at the U S V to get the wifi and password
can you explain a bit more about your issue
Hi there do i need a ttl uart to be able to upload the sketch?
If you use the same board as in the video (LoLin NodeMCU V3 ESP8266) TTL uart is not needed.
If the Port ia not being recognised? What should I do?
Have you installed the driver for NodeMCU ?
@@utehstr I installed the driver, but not sure if the correct one. I have to try a different cable, maybe that's the problem. Thanks for the reply!

Do you need to hold the flash button? Why some people are telling me that I need to hold that button?
I don't know about that and I don't have to hold the flash button.

My board keeps resetting and the server won't even start ??
if the board keeps on resetting you have 3.3v problem. You are not supplying enough mA to the board, these boards run 3.3v 300ma max. Also read something about the tx pin that is 5v on the arduino needs to be adjusted with a resistor to 3.3v
how to fix "error downloading downloads.arduino.cc" sir ?
Look here : forum.arduino.cc/index.php?topic=560963.0
that board suck you have to define pin Pinmode(D0,OUTPUT); didn't work other way like in Arduino Uno and its a low power board relay didn't work well with it
I cant download that .json file
