NODEMCU - Getting started with Arduino core 1. GPIO & Network Access

Node MCU can be best used by installing ARDUINO CORE on to it.Coding can be done with ARDUINO IDE itself.

This video is clear, concise and easy to follow for the absolute beginner. Thanks for putting in the time and effort. This is what I needed to finally start running the board after weeks of it lying unused because I didn't know what to do with it.

This is very nice session. On the spot and informative. No irritating background music and cheap animation. Keep producing good contents. Thanks !!

Just getting started with Arduino and ESP8266 12E and found your excellent video (I don't have anyone to help me).
It was pretty exciting to see my ESP8266 log into my home WiFi, and just thought I'd like to thank you for posting this video.
Eventually I want to control things through the web-browser, so I will look around to see what you have.
Anyway, thank-you very much!

Very good All the important stuff to see when starting with esp8266.

Sir You are just master in embedded and IOT I always follow you like a god.
Everything is just to the point and perfect!!
If I ever get a chance to meet you surely I will.

For those who got the Leaving... Hard resetting via RTS pin message, try keeping your serial monitor open while uploading the sketch. Hope it works.

Wonderful introduction. In a very simple way you have taught. Thank you.

Just for people's info, CS340 also works in windows 10.

Thank you so much for your video!! Without it I wouldn't be able to put my master degree project to work!

[RakshithPrakash]

Excelllent video, wish they taught all these in college

[charlesmerkel]

Thanks for your work on this tutorial. Everything worked fine for me except for my typing errors!!!!

[wallaceshackleton]

A good explanation, I actually understood what you were talking about, I wish I'd found this video sooner!

In my location (and this is probably true for many users) there are several access points only marginally within reach, and running WiFi.scanNetworks() twice produces inconsistent results, such that with the code as written the number of SSIDs returned by the first call may not match the number of SSIDs listed after the second.
This code - which calls WiFi.scanNetworks() only once - produces more consistent results...
...
Serial.print ("Nearby networks found :");
int n = WiFi.scanNetworks();
Serial.println(n);

Serial.println( "List of surrounding Network SSIDs....");
for (int i = 0; i < n; i++)
Serial.println(WiFi.SSID(i));
...

It may be that running the code repeatedly reports a different number of SSIDs each time, but at least the displayed number found will be the same as the number of SSIDs listed.

Great vedio thanks, how to use AT COMMANDS with NODEMCU

[prabakaranpalanivelu]

thank you sir for the wonderful introduction of nodeMCU.

[patrickmclaughlin]

Thanks for the info and video.
Since these boards are usually 3.3 volts I don't think you need the resistor for the LED?

[eswar]

Well doing sir thank you for doing these wonderful videos
