I like your tutorials. Everything is nicely chronologically described and most importantly everything works :)
I am a beginner in the field of MySQL, your tutorials have opened the door to this area for me. Thank you for your great work.
You're welcome 👍🙂
Finally a tutorial that really works! Thank you very very much!!
You're welcome :-)
I have an ESP 8266 (version 01) which therefore includes a GPI0 0 and a GPIO 2 (it seems to me that on this version is only usable the GPIO 2), but my concern is that all my sensors and other components are on the arduino card, so I don't see how to already transmit the data to the arduino card, and how to do with a single output to communicate all this to it, reciprocally from the card to the ESP
Thankyousomuch for this tutorial :)
You are welcome :-)
What a Great Tutorial! Thank you. I will one of your subscriber 👌
Can i ask for help about my project ? Coz your video tutorial is likely same to mine but I'm using mq gas sensor
Thank you :-)
@@waweyonor6052 Please send your question to this email channel, see the "about" tab.
@@utehstr okay thank you ☺
@@utehstr I'm a newby with arduino and esp8266. I'm using Mq gas sensors, the MQ7, MQ4, and MQ131. All i want to do is to separate every data that has been detected by that sensors into the localhost like in your video. Like this
ID l MQ7 l MQ4 l MQ131 l Date l Time
. Hope you can help me sir please 🙏
Thanks Sir. After a lot of frustated codes, this one works perfect. Very simple in order to send values from arduino to a localhost database via POST. I don´t know why with other codes I can´t do it, only to remotes databases.
Thanks a lot¡ ¡
You're welcome 🙂
Mas tanya, itu kalo datanya udah banyak harus scroll terus kebawah dong? Kalo mau dibuat 1 page cuma 25 data gimana?
Nice video as usual.
Do you have a vice versa project? The Nodemcu is the one who receives data from SQL database? Thanks!
Thank you :-)
I don't have a project like that.
It works :D Thank you :)
You are welcome :-)
I have multiple values to be sent. Please suggest changes to readDb.php files?
so is there a way l can combine this with the code to run a servo motor
I don't have UserName and Password when I open PHPadmin.. then what to set in the readDb file? please help
a good tutorial. saya mau nanya, bagaimana cara mengirim beberapa data sensor dari MCU yang berbeda ke dalam satu database? contohnya saya punya 5 MCU yang masing-masing akan membaca data 'penggunaan daya', kemudian data-data tersebut ingin dikirim hanya ke satu database. sehingga di kolom nomor pada database itu menunjukkan nomor MCU nya saja. terimakasih

Buen video, Como puedo leer datos desde MySQL con ESP8266 y esto controlar desde una pagina web que está en la nube?

Hii Admin. after 3 years of your Video
now the way of defining code has been changed and now not running. getting error .. can you please provide latest code?? in place of http.begin.
TE AMO
Gracias :-)
hello sir! Can you please help me? i have followed all your steps but i get -1 as a result and there's no data enteres in my localhost/myphpadmin... is there any other fix for this?
Did you fix your error? Because I am getting the same error as -1.
i have a project that use this system,
but some smartphone will connect to Wifi from NodeMCU.
Then the smartphone will open webserver from NodeMCU, and then input some data
but i cant save the data to database with this method, or did i need to online to use this method ?
Sorry I don't understand what you mean, can you explain in more detail.
is this project need internet to make it work ?
Thank you!!!!!!!!!
You are welcome :-)
maaf mau tanya klo untuk webhosting yg host diganti alamat hostingnya saja atau "alamathosting/ phpnya" ?
Saya belum pernah mencoba ini di web hosting, tapi dari beberapa sumber yang saya baca seperti ini : "alamathosting/ phpnya" .
ok coba aku cari2 dulu
Mas udah nemu belum jawabannya mas? Saya di kendala yang sama
kalo ingin mengirim data sensor suhu dan kelembaban, modul dht 22 bagaimana kodingan di "nodemcu"?
Akses dht22-nya, kemudian kombinasikan dengan kode yang ada pada video.
i want to know that data will be saved on computer or esp8266 module?
Data is stored on a computer.
Mas videonya sangat menarik, saya ingin bertanya jika menggunakan webhosting gimana mas? Apakah ada referensi yang bisa saya kunjungi?
Is there a pdf that i can download? The step. Cause i can't see Clearly the graphics
Have you watched 720p resolution? I made this video with 720p resolution to make it clearer.
i got this type of problem please anyboday know help me
exit status 1

Sir i have a question. Why is their a 200 in your serial monitor output?

Can you make a tutorial in ds1b20 and max30102? Same as your video

What programming language used in Arduino? Can I use python
Arduino code is written using the C++ programming language (On the Arduino IDE) and the library is written using C or C++.
Yes, you can program Arduino Boards with Python code. But I've never used it, maybe these links can be your reference:
- realpython.com/arduino-python/
- pythonforundergradengineers.com/python-arduino-LED.html
- create.arduino.cc/projecthub/smart-tech/programming-arduino-using-python-f3d2c0
Arduino boards can also be programmed using the BASIC language, here are the tools or IDEs that support programming Arduino boards using the BASIC language:
- gcbasic.sourceforge.net/Typesetter/index.php/Home
- www.mcselec.com/index.php?id=14&option=com_content&task=view
