Thanks m8! this worked like a charm!

great video. it helps a lot. thanks!

Thanks I didn't get the exact board for selecting ....from this tutorial I got this

Thank you very much for the good explanation! I was able to change the upload speed to 512kBaud without any problems and the flashing process was much faster.

6:09 Sketch uses 248,000 bytes (23%) of program storage space. Maximum is 1,044,464 bytes. 1,044,464 bytes are 1MB storage. Arduino Mega have 256Kb witch is 4x time less than this board, so its more than enough!

good slowly explain and clear voice thanks

Ey dude Thanks a lot for the video !!!, it really was helpful for me, really I do not know why it is difficult to find a good tutorial to explain which is the correct way to confiure these module. I was searching in the web and I spent a lot of time beacuse in some places doesn't expain completly and always miss some part to full configuration. I want to mention some things interesting: 1. Please make sure wich is your module model: In the video case and my case the model is a NODE MCU ESP8266 V3 Lolin ver 0.1. Because you konw exist another models and could be confuse to identify wich is the actual model you have because are fisicly similar another models. 2. Please make sure have a good micro USB cable (preferibly your original mobile cable). In some cases with anothers cables doesn't works. 3. Please make sure to have downloaded CH340 driver beacuse is the driver for Chinesse Arduinos or another not official electronic devices have these driver. 5. Please make sure donwload the property library. In my case I use 2.3.0 like video. Exist another new libraries but for muy does not work. 6. Configure properly Board model, CPU frecuency, Upload speed, Flash size like video and select port computer recognise. Bye

Thx!!! Great video!

how many relays we can connect with a nodemcu at the sametime for home automation ?

Hey I'm having a problem when connecting the NodeMCU V3 to my wifi network at home. Whenever I run WiFi scan (sketch example), it says no networks found. What should I do?

can you make a tutorial how to connect the Wi-Fi to the ESP8266 PLZ

It has built in wifi Just plug and connect

surely not optimal, but you could route jumper wires under the board if mounted on a single breadboard. If you go out in both directions you could probably access most of the pins.

Hi, I have same board. Whatever I try to upload, it just fails. Even on adafruit feather based on esp8266 it does the same.

can it be used with other older microcontrollers like ARM7 LPC2148??

How could you accomplish anything with such little space? What if I need to parse even a moderate sized api call?

ArduinoJson by Benoit Blanchon supports partial parsing and filtering among a multitude of other very useful tools that allow to parse large API calls and extract the useful information

Hello, I have a problem when i try to connect my board LOLIN v3 with 8266 to my computer. In Windows 7 it appear as unsupported device, and in Ubuntu 18 does not appear as a valid COM port. I connected using USB cable only and no other wires (assuming it must be enough to power via usb cable)

@3:50 users/BigDaddy ... lol.. i love it

Hi! Great video, thank you! Rebuilding worked out perfectly. But only if the board stays connected. After reconnecting or connecting with external power supply it does not work anymore. Do you have any idea? I work with the same module as you do: NodeMCUV3 an ESP8266MOD and Arduino IDE (recent version). Maybe you have any suggestions? Thanks in advance!

Hey sir thanks for the detailed explanation on this module could you build a project using this module that requires one to control appliances remotely using a custom built android app for the specific project? I have stumbled upon so many projects that illustrate this type of project but when I try with my board I can control the devices

The upload is only slow if the computer uploads slowly... Also I wouldn't recommend showing the example like this. The board will be powered with the USB and won't need to be wired to the breadboard. A beginner that forgot he has more then one 3.3v line hot running to the board will fry it and not even know why.

wooo woooo!

What you think why it is consuming so much space do you have to idea to get around it ? I think direct pin manipulation will be the solution and i also get invalid library error but nothing is effected that's why i just ignore it.

It's the WiFi stack, I'm guessing.

I am a great Fan of 8266. Would you please, do some videos on interfacing CCTV cams with 8266, so it can stream videos. One more project would be play from 8266 12E, internal 4M memory mp3 or wav files without using external active components. (No TF cards, and serial players) Any help would be welcome.. Please do some video on Range testing inside buildings.

Paul can you increase the memory on the board ?.

good getting started guide, i bought this too, but shocked to see it cant handle larger sketches?! im wondering what the diff as compared to writing using LUA? would programming via LUA be a better way for Lolin?

Hello Sir, Can you tell me how to pass the value from Arduino to NodeMCU ? I have problem when connecting the current sensor directly to nodemcu. The value produce is not same as multimeter. If I use Arduino, I got the value same as multimeter. Both I used same code. But different result. Can you share with me how to transfer data from arduino to nodemcu lolin??

nice zoom efects

I've posted before that in the Arduino IDE the port selection was grayed out when I tried to link to this board. The fix is get driver CP2102. I googled it and found it at www.silabs.com and the windows 10 installer installed it. The instruction to get this driver was on the back of the board in 2 point type. Wouldn't you just love to be one of those guys for whom everything works right out of the box?

Why i am getting fatal error for esptool while uploading program

I got my NodeMCU v3 board working a few months ago, no prob. I came back to use it again and couldn't get it to compile. I've spent a few hours searching for an answer without any luck, till I found the following site . It would seem that doing an update has a problem with more than one file in a directory. arduino-esp8266.readthedocs.io/en/latest/faq/a04-board-generic-is-unknown.html Hope this helps, Paul. My board is now working.

I had same error, but if different cable does not resolve, then in Windows check Device Manager to see if a Port appears when the device is plugged in. If you see a Unknown device, it requires a driver. According to the bottom of my particular device, I went to wemos.cc and downloaded and installed the CH340G driver. Unplug, plug back in, check Device Manager again. Back in Arduino editor, change Port to match. That resolved my problem. NOTE: I ordered 5 of these and 1 would not work despite everything being perfect. There is a video here on youtube showing how some of these may arrive with a defective USB chip.

So blinking led badic code uses 22%, 222k of 1M of Flash , and almost 40% of Ram! What a crappy tool is this IDE / compiler. For example, on Pic16f690 or 18f46xxx it takes 21 bytes of Flash and 3 bytes of Ram, so it uses ~7000 times less Flash. (On Cortex M3 chip Lpc17xx it takes 816 bytes due to registers init overheads.)
