Bro, your tutorial makes the thing nothing but easy. ❤ I was in the R&D phase for firebase system for last 3 days with no clue but you make it much easier. Really appriciate it.
Thank you very much, it works now Was trying for around 8 hours, with different libraries and clients, and none of them worked, but finally, in the end, this works
This is the first time I’ve seen a good firebase Arduino tutorial video. I liked your style. Will come back for more One tip for either you or google bug seeking bots. Viewing video on iPhone 14pro or any device with camera island basically acts like a bar that hides all the info behind it. Such as variable declaration or any details that would be necessary. So either make a band on side that shift your ide screen to right. Or google this one is for you. Turn on screen rotation on both sides. It’s embarrassing for you qa team and product managers who can’t see a ux flaw. Otherwise kudos to the maker of this content. Good job.
@@joedgoh hi while I'm using the getInt function, instead of 0 which is the correct value of the variable, I'm constantly getting 1. What could be the error here? Please help me. 🥺
I really thank this guy for this video From my depth of heart ❤❤ cause literally for 3 days I was like crazy mad on this firebase and finally I did it because of this guy Thank you from the depth of my heart 🙏🙏👍👍 Hats of you 👏👏
Very helpful video. If you have problems by compiling the scetch please mind that the LEDC declaration / API was changed in the latest version (ledcSetup and ledcAttachPin is now ledcAttach).

I was so confused why the value doesnt appear on firebase until I realised the wifi credentials was suppose to be my home/ phone hotspot' wifi so the esp32 can connect to the internet, what a head ache. thanks a lot!
Yes. You can export your RTDB by clicking the 3 ellipsis (...) on the right side and choose export to JSON. Open your Excel, go to DATA > Get Data > From File > From JSON.
I need help. I see readings in the seiral monitor very quickly. I connected my computer to the same network and the password I put in the code. I put the link and API key in the code correctly, but it shows me null in the firebase. What is the problem? Are there platforms through which we can communicate with you?
I have problem in read the data from the firebase's real time database. Only string is readed properly integer and boolean type is always readed as zero and false respectively and sometimes boolean type is not readed. Pls solve my problem. I have written the exact code and followed the exact all steps which you have followed.

How many times can a esp 32 board fetch values from firebase RTDB in a second, given it a strong internet connection. What's the limit, can it fetch a value every 10 milli seconds

Very educational video congratulations, when I'm running the code it keeps giving a problem in the function ledcSetup(PWMChannel, freq, resolution); and ledcAttachPin(LED1_PIN, PWMChannel); it says that the variable was not declared correctly, what could be going wrong? and I'm also unable to see the sensor data in the database. If you could send the code it would be a great help.
hello sir, thx for your tutorial video it really help me alot but i have some problem when i try to read boolean data from firebase to control my LED, there is error message called "connection refused" every 8 times tries to turn on/off my LED. so if i try to turn on/off after 8 times tries, i got that error message. can you help me to fix it? Thx.
PLEASE help me. After 60-120 seconds it stops to work and update data.. Like it's frozen But in first seconds it works well, code very simple, just a Set boolean
Hello sir, After approximately 10 minutes of sending data to the database the connection will be lost and display "connection refused" why does this happen?
Baket po hindi ako maka connect sa firebase sabe po sakin na kulang dw yung mga credentials ko nilagay ko nmn po yung api key and link sa database pero kulang daw mga credentials ko

Muchas gracias por estas enseñanzas. El año pasado, despues de mucha investigacion hice un proyecto que funcionaba perfectamente, pero algo ha cambiado en firebase que ya no me da acceso. Y en este video creo que esta la solucion. Podria enviarme el código, por favor?. Gracias.-
El código lo puso en la descripción del video, es su página web. Yo pasé por lo mismo que tú, hace unos años usé Firebase para un proyecto y ahora que lo volveré a utilizar, noté que varias cosas cambiaron, especialmente lo de la autenticación y la verdad este video fue muy útil para entender nuevamente su funcionamiento.
While this is a great tutorial. It completly misses the point of a (Real Time Database). The way this is set up is a polled database configuration. For (RealTime) you have to use a stream callback. This allows you to get INSTANT changes on your ESP32 when you change that value in the database. Install the library and check the official examples for more details. (Edit) - I see you got it right in lessen 6. Good job.
unbelievable amount of errors in this code, ldrData undeclared voltage undeclared analogueReadMilliVolts and so much more.

What are you talking about Jacques Mulder???? This tutorial helped thousands of students and professionals. I put it online so it can help more people who are in need of free lessons. This code worked for all of them. I am replying to your comment because you are not helping others with your false claims. Do not say that I have an "unbelievable amount of errors in my code" like undeclared ldrData, voltage, etc... because you are wrong. Please watch the lecture again carefully so that you learn from your mistakes... Just to put you into the right perspective, you are watching a FREE and step-by-step lesson that I worked hard to create and this is WORKING 100%.

Yes. You can export your RTDB by clicking the 3 ellipsis (...) on the right side and choose export to JSON. Open your Excel, go to DATA > Get Data > From File > From JSON.
In my case, every time that I read a value from firebase a lot of times, the esp3 gets frozen for 1 min.
