Getting Started with NodeMCU V3

Big daddy😳🤨🤨🤨🤨

The folder is kinda sus tho

Users/BigDaddy got me 😂😂😂

BigDaddy.

I approve.

Apparently ledPin is a huge variable😂

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.)

You said the link would be below so we could copy it?!?!

That's not nodemcu. Thats just plain old c...

Paul can you increase the memory on the board ?.

sorry but i dont see in the link down below

can you share the schematic?

The introduction is good , but the example is not, because it is basically meant for WIFI, I was expecting WIFI example

wher is the json board link , you moron !!!

Thumbs up > onto part 2

Why i am getting fatal error for esptool while uploading program

why is your user in windows named "bigdaddy"?

nice zoom efects

sir
i have a problem. Please help. The program in my 'nodemica' does not show 'port' after I connect it. What to do? Please don't say ....

What is this good for ? It's sold on amazon 15€ for 3, that's like 4€ per unit..

Users/BigDaddy

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

i cant copy the link into my ide?

There appears to be a freight train in your NodeMCU.

I might be a bit late to the video, not sure if you still read this comment, but no point in not asking I suppose. I want to write assembly code for this board, do you know how to go about it, and if so, can you please send me some resources to get started?

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)

the storage is so small

You sound like Joe Rogan

wheres the part about installing the driver?

POR FAVOR
pode me ajudar? esses erros foram encontrados quando eu tento carregar:
warning: espcomm_sync failed

error: espcomm_open failed
error: espcomm_upload_mem failed
error: espcomm_upload_mem failed
é defeito? vou ter que jogar no lixo? : (

Espcomm fail help me !

Thanks m8! this worked like a charm!

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!

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

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

my board says on it to use 9600

wooo woooo!

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??

great video. it helps a lot. thanks!

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?

Does it have built in led ?
