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

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

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

[toHeroOffical]

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

[MichelleShum]

Thanks for your guide. It's very helpful

[Nwayne]

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

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

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

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

[havidfebrim]

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

[usamakhalid]

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.

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

[projectovernight]

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

[kienvu]

my serial monitor doesn’t show anything on it

[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.

[robertenachescu]

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.

[TheDarkforce]

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

[teckycloud]

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

[jasirjawler]

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