Getting started with NodeMCU (ESP8266 tutorial #1)

★☆★🎆🎆Second tutorial 🎆🎆★☆★

★☆★ SUPPORT US WITH A SIMPLE TIP ★☆★

In this Tutorial I explained some basic information about ESP8266 inorder to help you understanding how to use this super cheap Dev board. Also I showed how to configure Arduino IDE to program ESP8266 by insterting the following link in additional boards manager URLs.

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

Nice video, but please for the second get rid of the music in the background or lower the volume a lot... so distracting!! -and irritating tbh-

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="";
}

Thank you so much for this very very helpful video! but please, consider using an anti pop filter on your microphone.

Be aware that most (all whom I have asked) ESP8266 sellers in Aliexpress sell 30mm wide board which doesn't fit to 400 holes/tie points Breadboard, it is too wide. In amazon the still sell 26mm model. So be aware!

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?

Thank you so much! This has been the most helpful resource I've found for a neophyte like myself!

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

[addisugebremichael]

i need a refresher and this is the best video

[Bicho]

hi mega das. that's a great video. thanks a lot, but what next ? i need (tutorial #2) please

[abdullahguler]

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.

[NotShanny]

Looking foward for a tutorail 2 ! Great job !

[frankwas]

you should get a pop filter for your mic

[danieljohnsopardenilla]

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

[lwo]

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

[silentscope]

the project code is no longer available

[williamgraham]

Please drop the music, its distracting.

[teoncool]

Love the video! What usb cabel is required?

[DDTMAXX]

Very many thank's, this video was very helpfull!

There is no link for project code, I wrote as much as I could because video is blurry, replaced DO with LED_BUILTIN and it worked.
