Hello Sir, I got to understand the working of this project Setup. But in this Setup the data is sent from NodeMCU to Arduino if im right, how can we reverse this so that i will be able to send the data arrived from arduino to the firebase using wifi
Hi sir I have a question umm i'm really new to these stuffs umm why didn't we use the rx and tx pins of the arduino and the rx and tx pins of the nodemcu esp8266?
Hi, I used your code and followed your instruction but I notified that "ESP8266WiFi.h: No such file or directory", I also downloaded a corresponding library but It didn't work. Can you inform me of the proper library for this program? thanks so much!
i connect one sensor to A0 of analog input in the nodemcu esp8266. then i will put another sensor to A0 in the nodemcu but there is only one A0 of esp8266. Is it possible if i connect other A0 to Arduino uno r3 the A0 then send it to blynk?
Hello, I have simply followed all your instructions and my arduino and nodemcu working properly but, as you mentioned in video, Rx should be blinking but in my case, Tx is blinking... so can you help me with problem? And also, will this project work with arduino Yun? Please reply.
how about serial communication between arduino uno and esp32? im already try with the same code as yours but there is an error said this " exit status 1 request for member 'begin' in '1', which is of non-class type 'int' " can anyone help me?
Hello My Name is Mohammed and I am part of a robotics team in BDCHS I have been trying to get an arduino Uno with a RTC module and NodeMCU like your ("How to make SoftwareSerial Communication between Arduino Uno and NodeMCU") work for our competition and I can not get it to work if there is any way could you please help.
Replace SoftwareSerial ESP8266(D2,D3) with NodeMCU(D2,D3). Do the same for all other SoftwareSerial functions (f.i. replace ESP8266.begin(4800) with NodeMCU.begin(4800) ). It is clearly shown in the video at 17:23.
This way you cannot send data from Arduino Uno to NodeMCU. NodeMCU's Rx pin works only on UART0. However, it will work if you want to send data from NodeMCU to Arduino.
Hello! Would it not be possible to connect the RX and TX pins of Arduino to RX TX pins of NodeMCU? It is just a question because i use the digital pins 2 and 3 for other purpose in my project.

In case if we are just using the ESP8266 module not the NodeMCU, in that case can you tell me what pins of esp8266 will be connected to 2 and 3 of arduino and what will be the changes in code?
nice question bro ? Anyway you can Google for esp8266 download and upload code process as it will show you the schematic board diagram that let you perform the transmit and received data along with pin number, the code on the other is not going to change anything

Are you helping people to destroy their devices ?? its okay to receive 3.3v from esp to arduino . BUT dont send from arduino to esp like THAT!!! you need a "5V-3V IIC UART SPI two Channel Level Converter Module" also you need to learn how to how to split multidata from arduino sensor and send ensure they got recived well without problem
I'm trying this but every time Arduino and nodemcu communicate the nodemcu gets disconnected from internet. And to connect them again I need to restart/reset the module
Several errors in the terminal...ESP8266 should be NodeMCU ... check the download.ino or look on the monitor @ 14' 26" Arduino Tx should have a level change from 5v down to 3.3v with a level changer unit or a 1K and 2K resistor. 5v inputs to the NodeMCU could damage it.
In my video I don't connect but you can connect if you only need one power source connection and nodemcu is support 5v as well but make sure you connect to 5v of node MCU not 3.3v cuz it will damage the board
it worked really fine, thank you for your support, now i would like to send two different readings from two sensors, do you have any tutorial about this?

never said, in the code there is a esp8266 but when his monitor show us you can see NodeMCU.

2 way communication in a sametime? Esp8266 to Uno and uno to es8266
@RedTron - This won't damage nodemcu, right? Asking because ESP works on 3.3v while UNO on 5v.
So far so good although it won't giving any quick damaging, in theory it is a bad idea but in reality this working fine and might last long
Thanks for the question anyway
Thanks.. yeah, anyways here UNO is not sending to esp...
If you are paranoid, then consider level shifting the 5v to 3.3v and vice versa. It's good engineering practice.

there you must use voltage divider from 5v to 3v3
