Thank you very much, for this great help and saving time. I was searching the method to split the serial data for almost two weeks and here I got the perfect solution.
Hey dear seems to be great totorial but i want to ask one question i have two sensors connected to uno and then i am sending its data to firebase using esp01 via serial communication but when it recieved at firebase they are combined one after to the other , as their any way to separate the reading for the both sensors in a separate row each contain only one sensor reading and then so on please need your help thanks in advance
On the Arduino side, how would you convert data* variables (string) to useful variables (int / float) in code? The only way I was able to do it was with a character array and parse using strtoul... I would prefer your method however because each data is specifically indexed. Excellent content btw **
Hello, great video that works very well between two esp8266, but when is it for communication between two ESP32? If you can enlighten me? The libraries are different, I think for the ESP32 the procedure is quite different. It would be great of you if you have already touched on this subject to tell us more. Thanks for your help.
Hello sir! Your work really helped me in my studies and projects. If its possible, can you show how to have two way communication where an arduino will request data from another arduino before it send them. Thank you!
Excellent :). Very informative. I have a question. If I want two-way serial communication between two Arduino's what do I need to add in the main loop to distinguish between transmitting and receiving. I don't need a whole sketch. I'll go into the details myself. Thanks
You can watch my first video about nodemcu arduino serial communication the basic of two-way communication. The program for nodemcu in that video also worked for arduino. You only need to change software serial pin, change D1,D2 to 10,11 or other pins on arduino. Thanks
Hello. Great tutorial video. Can you also make a tutorial on how to send ultrasonic sensor data from arduino uno to esp8266 and then send that data to firebase please ?
Exelente informacion, entendí todos los gestos que hiciste con el tipiado del código, los compilé sin errores, pero no logro que se comunique, probé la librería SoftwareSerial y no logro que transmita, el conexionado esta bien, que otra cosa puede estar mal?, muchas gracias al que me pueda orientar.
Hi Thankyou soo much for this great tutorial in this video you have sent serial data from Nodemcu to Arduino can we try the opposite like sending data from Arduino to NodeMcu ? using the same codes ? I have been trying it i do read values on serial monitor but when i try to save those values on a local integer on ESP8266 i get 0 in return Please let me know what could be wrong meanwhile i will try to use your method Thanks in advance
@Catur Pebriandani THANKYOUU VERY MUCH This code works absolutely fine with nodemcu sending values to arduino I have been struggling on transfering serial data recvd from arduino on esp and then using espnow protocol to wirelessly send the rcvd data to anther esp this is example saved my project :D

you absolute beauty
عاشت ايديك يالمغربي 👍
Thank you very much, for this great help and saving time. I was searching the method to split the serial data for almost two weeks and here I got the perfect solution.
Glad to hear that sir :)
WOW, Channel ini sangat membantu sekali dalam pengerjaan proyek saya.Terima kasih banyak CP
Hello, great video tutorial, and your work really helped me. Thanks Bro.
You are welcome sir
very useful tutorial, I was searching splitting data of serial read, from many days
thanks
You are welcome sir
thank you sooo much you just completed my project
Thank you so much for sharing the knowledge... You really saved many people's brain... including me.. Thanks Sir !
Nice solved my problem thanks a lot
Hey dear seems to be great totorial but i want to ask one question i have two sensors connected to uno and then i am sending its data to firebase using esp01 via serial communication but when it recieved at firebase they are combined one after to the other , as their any way to separate the reading for the both sensors in a separate row each contain only one sensor reading and then so on please need your help thanks in advance
Thanks man. You saved me. I was trying and searching for exactly this thing from last 10 days. Thanks again. keep uploading.
Glad to hear that bro :)
Great video, do you have any videos using char array instead of String?
On the Arduino side, how would you convert data* variables (string) to useful variables (int / float) in code? The only way I was able to do it was with a character array and parse using strtoul... I would prefer your method however because each data is specifically indexed. Excellent content btw **
Hello, great video that works very well between two esp8266, but when is it for communication between two ESP32? If you can enlighten me? The libraries are different, I think for the ESP32 the procedure is quite different. It would be great of you if you have already touched on this subject to tell us more. Thanks for your help.
thank you , you saved my project
I tried it to Arduino to Nodemcu but it just output question marks? What do you think is the problem there?
Hello sir! Your work really helped me in my studies and projects. If its possible, can you show how to have two way communication where an arduino will request data from another arduino before it send them. Thank you!
Excellent :). Very informative.
I have a question. If I want two-way serial communication between two Arduino's what do I need to add in the main loop to distinguish between transmitting and receiving. I don't need a whole sketch. I'll go into the details myself. Thanks

If I want to change Arduino to be a data sender and Nodemcu to be a data receiver, what would it be like?
Hello. Great tutorial video.
Can you also make a tutorial on how to send ultrasonic sensor data from arduino uno to esp8266 and then send that data to firebase please ?
You just saved my life
Vary good 👍
will it work for if the integer values from transmitter are varying?
really helpfull also safe my project
thaank you so much
Hello Sir! Is the same method from Arduino to Node MCU??
Yes, it works for both programs. both have the same code.
Exelente informacion, entendí todos los gestos que hiciste con el tipiado del código, los compilé sin errores, pero no logro que se comunique, probé la librería SoftwareSerial y no logro que transmita, el conexionado esta bien, que otra cosa puede estar mal?, muchas gracias al que me pueda orientar.
Is the a way i can parse the data without using substring
I need the output to be an int or float
You only need to convert the data after parsing
sir
Hi Thankyou soo much for this great tutorial
in this video you have sent serial data from Nodemcu to Arduino
can we try the opposite like sending data from Arduino to NodeMcu ? using the same codes ?
I have been trying it i do read values on serial monitor but when i try to save those values on a local integer on ESP8266 i get 0 in return
Please let me know what could be wrong
meanwhile i will try to use your method
Thanks in advance
