Serial communication between Nodemcu and Arduino - Learning Arduino 06

Hey brother, it's possible if i change the Rx and Tx pin on Arduino to another pin?
Lets say pin 2 as Rx and pin 3 as Tx. If it can it means that we have to instance the SoftwareSerial object ya?

thanks, the first line after loop() was just what I needed. very good!

Brother if we look to connect the hardware serial of arduino board to hardware serial of node mcu (gpio 1 and gpio 3) then what would be the baud rate (in node mcu) ... i mean like in this video u've assigned 9600 to software serial pins and separately for node mcu to pc at 115200. But in my case will there be only one and that to be at 9600?

Thank you so much for this tutorial. You explained it beautifully! I've been sweating tons to try and make this work! 👍

👍👍

Hi, can i use also the MOSI/MISO pins on arduino. RX/TX is already connected to other stuff. What do i need to change in the code?

Hi, I'm from Sri Lanka. Can you explain how to assign two or more sensor values to the variables on the NodeMCU side?

Can i connect Arduino mega with NodeMCU esp8266 and then connect to thingspeak to visualize sensor data?

How can we calculate data in nodemcu coming from arduino via serial communication

Brother... Tft display par reading nahi horaha he serial monitor per full work kar raha he... Pls. Help

Thank you so much bro
Completed my project peacefully ❤️

Can you provide a link for the codes please ?

rx and tx of nodemcu are gpio3 and gpio1 why u havent used these two pins

sir,
how to send multiple data sir ( i mean if we use more numbers of sensors)

Thank you so much sir. I hope next intresting video coming as soon as possible.

sir, how can we transfer 3 or more sensors data from arduno to node mcu

Sir I'm using nodemcu esp32 will it work in this manner only?

The video explanation is simple but when i have done it didnt show the msg on the node mcu serial monitor.Kindly help

Nice Explanation

how about the communication between Arduino Mega 2560 and NodeMCU sir? is it the same or is there something that i need to change here? thanks!

Sir, as the Nodemcu board takes upto 3.3V and we are connecting it to arduino which outputs 5V, won't it damage the NodeMcu ? Or is it safe to directly connect them with Rx & Tx pins without any resistance?
And, if I use resistance to get 3.3V on NodeMcu side, will the serial communication work properly??

I was facing more problems

No use

Is Voltage difference going to make any issues for long term usage

It's damage my Node mcu board. Because GPIO pin work on 3.3v. 😭😭

Can this same method be used for arduino nano?

hello how can i send 2 data from arduino to nodemcu? i can send 1 data but not 2, pls help

Thankuu so much yrrr😭😭😭😭

Great video nice

Well, I used more code to transfer data from arduino at nodemcu and then display into webserver and finally thingspeak but your video make so simple the things I will try it

If we wanna send data from nodeMCU to Arduino ... will this work or I have to make few changes??

Great video man. what i want to know if this is possible with esp32 camera

Thanks bro now I learned how to use serial communication for microcontrollers.

Hello sir. This worked for me, but now i want to send my data further to thingspeak. I have received 2 sensors data from arduino to nodemcu. What should i do?

How can send the dht11 data to firebase after receiving from arduino

Hey
Thanks for the video
But I want a notification to be sent through blynk app after this serial communication.
I want to use both arduino and nodemcu

good

If we do not define rx and tx pin in arduino code then default serial communication pin of arduino is selected??

Keep going! very good explanation!

I am facing error like " D1 was not declared" anyone pls give some info. to solve this

If i publish this data from node mcu to adafruit io.. it keeps laging for example. If the Arduino gives a data like 9000.. at the mcu its, getting -- 9 "lags for five sec" then 0 "then lags" 0 ,0 its prints each digit witha delay its not printint the whole like 9000

i was not able to send the data to nodemcu but after watching this video i am getting the data on nodemcu
Thank You

Sir, is it possible to interface aurdino uno with ESP32 dev. Board..?

Can you also do esp send data to arduino???

谢谢师父，非常好的讲解！！！

I am receiving the sensor data(1/0) correctly on NodeMCU, but the "if statement" is not working on that data,, plz help Sir

Thanks buddy...

Getting this Error: 'class SoftwareSerial' has no member named 'Serial'

Nice
