• Description:
Often times we need to report data collected from sensors to a 'central' location for visualization. Typically, we use cloud services such as Thingspeak, myDevices Cayenne, or Ubidots for this purpose. However, it is possible to dedicate an ESP8266 to carry out these tasks.

#ESP8266 #Arduino #Tutorial

The startup WIFI status output to Serial, generates a invalid response which causes the whole communication to be out of sync. I'm getting "delayed" values, meaning the if I request a web update, then I get the values from the update before.
I solved it by emptying the serial buffer at the end, ensuring that nothing is left. Insert a Serial.readString(); just after server.send

This was the tutorial that saved my life, thank you so much. The explanation and steps were great!

[paulgibby]

Thanks! Another great video and project. All the best

[kunalsanghvi]

Your video actually helped a-lot, thankyou for making a wonderful and instructional video.

[neerajgupta]

what changes do I need to make in the code if I don't want the request part in the program?

[sinchanagupta]

Thank you for the wonderful video. I finally understood serial communication. Is there any way, I can include port number in the server? Because I'm using this code along with Node.js to create an express server.

Serial.print puts data to serial port and it's a loop then between Arduino and ESP8266. Is there any workaround or just not use Serial.print at all for debug statements ?

[TheGood]

Since that esp 8266 uses 3.3v in their ports and Arduino uses 5 V, isn't possible to damange the esp ?

[Leo-vyfz]

hey can we do this using esp32 instead of esp8266what are code differences

[Imancu]

Excellent video! keep up the good work!

[simonlukas]

Does this also work if i only have one usb port on my Laptop? What can I do if the esp8266 registered in my network but the local webpage does not Show anything while loading ifinitly?

[thennz]

can i assign tx, rx pin to other pin in arduino bcoz im already using that tx, rx for other purpose.

[madspoulsen]

If you're tired of waiting "forever" for the response, speed up things a lot by adding: Serial.setTimeout(20);
in your Setup method, on both the Arduino and the ESP.
It will be lightning fast, but perhaps you need to adjust the timeout value. Also running 115200 on the serial port speed is great.
Thanks for the video by the way, ACROBOTIC. You saved me a lot of time with this simple setup!

I have a problem when opening the webserver with the IP adress. It takes a few minutes to show the sensor data on the page. What could be the issue?

[jktipan]

Excelente mi estimado saludos desde Ecuador, una consulta en el Node MCU esp8266 como envío los datos hacia thingspeak ya qué te permite generar gráficas

[ayushmishra]

How many sensor data can be send through DynamicJson

[TresnaWidiyaman]

Its work !
Other time i try to modify this program, and remove webserver view to be display json data on serial monitor.

I save the json program in void loop, but i have a error in my program. Nodemcu can't read the json data from arduino.

Can you help me ?

[jelkabisa]

Hello,

Please I really need your help, I want to finalize a project but I'm stuck with sending information from one board to another, could you please help? maybe something is wrong with my code.

[cceungf]

Thank you
Please I have question
Can we use software serial to send data like time and RFID card uid instead of arduinojeson

[tapsonkadakure]

Great video and its easy to understand, however i ran the code on mega, the url/web request trigures the function handleIndex and data is sent to mega but the esp cannot deserialise the response it says failed: IncompleteInput"
