Getting started with NodeMCU (ESP8266 tutorial #1)

You have forgetten one step in Arduino IDE after setting web address under File --> Preferences menu. One needs to instal the boards: Tools --> Boards --> Boards Manager --> ESP8266 --> Instal

How many pins in node mcu?

Not subscribing just because of the music

I'm very newbie I'm getting an error during compilation. Can you upload the .bin file of the project? It's a perfect design, I congratulate you.

what is sheep?

😳 nice thanks!

Hiya Dr. Nick!

I plugged in esp in my laptop and started to smell like something is burned

could not watch this shit!! just because of the annoying music

I have a esp8266 nodemcu, I want to use it only for Matrices of Led ws2812 (neopixel);I do not have wifi, then my question is I can use it in my project canceling the wifi, or I must install some additional firmware

Yo tengo un esp8266 nodemcu,lo quiero utilizar solo para matrices de Led ws2812(neopixel);yo no tengo wifi,entonces mi pregunta es lo puedo utilizar en mis proyecto anulando el wifi,o debo instalar algún firmware adicional

Love the video! What usb cabel is required?

Project code is no longer accessible.

i need a refresher and this is the best video

Can you please explain why SerialData+=data and not SerialData=data?

shut the fucking music off gggrrrrrr

Dreadful distracting Music no good for people trying to learn.

you have made this video in english and using some other language on your computer it is very confusing

Why that stupid music? Why that bad sound?

Very cheap sheep

This code didn't worked for me.. The led is always remaining on after uploading

Thank you for sharing.

This video is really usefull 👍🏻

Great video! Time stamps would've been nice tho

How to make it work like a rubber ducky

Just stoped watching this "tutorial Video" further, because of the stupitidy of the YT channel !!! this is absoltely not a tutorial video. This video is only created to make some commerical to a very very expensive online shop. Thumb deep down !!

Thank you for the video . i try to run the code but, i receive an error that "D" is not declared in this scope.

closing noisy bgm

switch off this music!!!!!

Are you Filipino?

Wait a second, the guy even buys the thing on the tutorial? wtf

Sir, if nodemcu is fitted in box then what to do so it will not be overheated

fantastic video info... thanks...:)

No. Bro its not that easy. Drivers does not get installed auto.atically. and port option is disables in arduino tools menu

properly speak in your natural accent. Non sense fake guy

Thank You!!!;

Not cheap.

Nice tutorial, thanks! Since the link to the code is broken, here is it (more or less):

char data;
String SerialData="";

void setup() {
Serial.begin(115200);
pinMode(D0,OUTPUT); // pin D0 corresponds to the internal LED
}

void loop() {
// read the string from the serial monitor (the console)
while(Serial.available()) {
delay(15);
data=Serial.read();
SerialData+=data;
}

// turn LED on or off (and send message back to console)
if(SerialData=="on") {
digitalWrite(D0,LOW);
Serial.println("LED ON");
}
if(SerialData=="off") {
Serial.println("LED OFF");
digitalWrite(D0,HIGH);
}
SerialData="";
}

I am using Nodemcu esp8266
With that I am using 4 channel relay board. But this is operating as Active low relay.

I want to operate it as Active High
How to change the board

Please use true accent

Would you be able to provide the script used to turn on and off the LED loop? The mediafire link is not working at the moment.

Why do SO MANY electronics tutorial videos insist on irritating music in the background, so unnecessary

Hello bro
First of all thank you for giving us such a beautiful and informative video.
I had some questions about ESP8266 NodeMCU v3. If I want to make a repeater with it. So my question is
1 / What will be the maximum range of NodeMCU repeater?
2 / What is the maximum data speed of NodeMCU WiFi?
3 / NodeMCU repeater maximum number of people can use together?

Please drop the music, its distracting.

thank U

Hello, my ESP 8266 r3 module when loading the code it says: "leaving....hard resetting via RTS pin... ". Please help me.

what is the max range covered by node mcu 8266 in meters

I can't understand the introduction you gave !

you can send PageIndex library to me ok.thanks you verymuch.

where is the next tutorial!?
