Keep growing brother. Great video content. I have subscribed to your chanel as 168th subscriber. Awesome

[@EucliffeFT]

Thank you so much :'D, been looking for this for quite some time now xD

[@koupohroyandredavid2639]

u saved my life bro

[@talhaeroglu4063]

you are a good guy

[@MichelleShum]

Thanks for your guide. It's very helpful

[@N19wayne]

Thank for your guild, it's very helpful. :D...!

[@mudit6306]

i uploaded the code successfully but it is printing 115 instead of 50... i dont know why from where does this data coming from...

[@0toHeroOffical]

thanks for the tutorial its works fine in arduino UNO.but not working with arduino mega although i have checked pin diagram twice please help its urgent thanks in advance

[@ths.ks.lehoanggiatruong]

how to send data from NodeMCU to Arduino ? thank you

[@zackam5870]

I have a question. Is it possible to use similar code for arduino mega with nodemcu? I'm not buy yet the arduino mega. I need to know either it possible to use this technique or not. Thanks

[@VeritasiumOP]

Yes, Arduino mega will also work

[@sandeepprajapati2188]

Hello Sir, how can we read multiple sensor data from arduino, sensors like ph temperature, mq5, mq7 connected to arduino and they are sent to nodemcu, and further it is sent to Thingspeak, kindly guide about it asap

[@prasannagawade6940]

have you completed above project

[@avirupmondal4480]

Sir can u help me to recieve data from soil sensor using arduino on mobile phone with the help of node mcu and blynk app

[@joelserrao1078]

Did u make any progress??

[@jktipan87]

I can send data from arduino's sensors to nodemcuesp8266 and display the data on the thingspeak , can work for you

[@MrREIVAX2]

Hello, this would be more interesting to do it manually with an HTML inside the code of the NODEMCU and pressing a button on the website send the 50 or another number and turn on a led by TX Rx Arduino, the idea is to have infinite outputs in the NODEMCU

[@Learnorz]

Hi MrREIVAX2,
Yes that's a great idea. We have implemented communication from Arduino to NodeMCU. The other way is also possible. Interested in controlling Arduino from RaspberryPi then check this -->mybtechprojects.tech/control-arduino-from-pi-using-gui/

[@jktipan87]

I use sensors like dht11 and mq7, mq135 to send data via arduino to nodemcu and the data displays on webserver and thingspeak, bit this video works to me

[@havidfebrim3523]

i'm sorry, i cannot find the coding in your blog, can you sent the code to my mail?

[@usamakhalid1860]

Can you please confirm if we need level shifter for serial communication between Arduino and Node mcu? As arduino signal have level of 5 volts and that of Node mcu have 3.3 volts.

[@tamizhdiynaveen1354]

Usama, there is no need of level shifter for serial communication

[@ronaldvinasoliva4470]

@@tamizhdiynaveen1354 in fact it is needed for protecting nodeMCU, you can use a voltage divisor with 2 resistors

[@projectovernight9760]

sir, i am not getting any output on serial monitor. please help me

[@tamizhdiynaveen1354]

Check the USB ports or interchange the usb ports

[@syedabubakar6858]

@@tamizhdiynaveen1354 nothing happens even after exchanging the usb ports

[@ciposum]

Thanks! Not working for me. I'm not an electrical engineer.. by intuition and luck I plugged GND of arduino e nodemcu and worked fine.

[@jeremytiempo9639]

do u have a schecmatic diagram for this?

[@robertenachescu8368]

Guys, if it's not working, try connecting the RX on the Arduino to the TX of the NodeMCU and the TX of the Arduino to the RX of the NodeMCU.

[@jktipan87]

That's correct

[@teckycloud2642]

I am complied everything by your guidelines. But no output without any errors

[@tamizhdiynaveen1354]

Try with other USB ports

my serial monitor doesn’t show anything on it

[@ElectroSpecies]

Don't use the circuit ।। May be the person have minimum knowledge about the voltages of different borads ।। Please use a voltage devider between the pins of tx pin of the Arduino and rx pin of the nodemcu

[@timetimes4u186]

Not working for me 😑 why?

[@TheDarkforce95]

do you have the tutorial for mega ? i simpliy replicate this code to be using with mega but it could not work. no 50 in serial monitor of nodemcu, just a bunch of unreadable symbol

[@tamizhdiynaveen1354]

Hi Abdul, Thanks for watching this video. Check whether the baud rate is the same in both nodemcu and mega.

[@TheDarkforce95]

@@tamizhdiynaveen1354 it is the same baud rate for both mega and nodemcu. thanks for this i finally can figure out the data sending from mega to nodemcu must be in form of string or else that i dont know. your code somehow cant be used on mega. i dont know why and it took me 6hours troubleshoot the code without success. but i do my own code and the data sending is work after that. any thing you can comment on that mr ?

[@jasirjawler7749]

you can only transmit 8 bit data by this method....

[@window.location]

He says 9600 bits per second
Which is actually wrong
It baud rate and it not measured in bits
Baud rate = symbols per second

[@tamizhdiynaveen1354]

Yeah, it's right. But we use 9600 baud rate(i.e maximum 9600 bits per second can be transferred) for effective communication between Arduino and nodemcu.

[@window.location]

@@tamizhdiynaveen1354 i don't think 9600 is perfect for communication b/w node and Arduino there is more rate available but it is another mater
I am saying there's a lot of difference b/w bit rate and baud rate
And u are arguing once again bit and baud are same which makes no sense plz Google first
Search bit rate vs baud rate

[@shadowlessstudios]

why do have to write "s" ? dont get it ??

[@2811andi]

it dont has to be s. Device A has to send a message to device B to trigger an answer - in this case the message is the character 's'

[@pokpikchan]

You need to 3.3V for ESP8266. This is fake
