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.

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.

@edgarwideman737 Рік тому

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.

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.

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%. If you don't even know how to say "thank you", it is fine, just please don't put comments that are not helpful to others.
