Great content, please do more of these
Hi Joed! Its really glad to learn about your IoT Dev Learning Path from introduction 01 until now. I hope you continue this path/playlist and could tell us about how to store data periodically. For example, the system stores each data sensor in every 3 hours, and we can retrieve its data and filter it based on datetime (day-by-day) through Android Studio. I hope you could explain it. Thanks!
Thank you! I appreciate your comment. 😊 I wish I could continue this playlist as well. As of now, I am working on the SunFounder Arduino playlist., probably when I reach the IoT part of this course, I'll continue the esp32 as well.
You're a genius bro. You helped me with my IoT project. i was going crazy but thank god i found your channel
You're welcome. Please share 🙂
Lovely edited and comprehensive tutorials broken down into manageable chucks. Thanks so much!
Thanks!
Thank you that was very helpful
I'm taking Software Design as a Computer Engineering student po and ang helpful po ng videos niyo sa current project namin for completion this semester. Maraming salamat po
Thank you! Pls share 😊
Great video! I'm going to build a I-V curve tracer for FV pannels using ESP32, i hope i can plot the curve through firebase data in the app that i'm going to build.
Very well structured tutorials. You have a great talent for teaching. Keep up the good work :)
Thank you!
lovely video ur very good at explaining sir thank you
Thank you!
Hi, if I don't want to use the button every time I want to upload the data, how I should do the code? I would like to display the upgraded data without the necesity of using the button.
Thanks and nice video.
Hi Joed. Great tutorial very clear thanks. How would I go about creating a web App for controlling ESP32 GPIOs
Thanks, bro......
I recently make a project like this but using Flutter instead. Can you give me some ideas about the new features.
hello po gumawa po ko ng database na authenticated user lng pwede maka access.. pano po ma read ung realtime database kapag sa esp32.?
Ty sir , you help my homework
Welcome!
When choosing get started with real time database in the Firebase assistant window, only java is displayed it doesn't show the option to do with kotlin. Any way how to fix it.
Pls make a tutorial on Firebase Firestore so that we can control and monitor the stored data in the database using our IOT application.
For my project i need to store the updates in any variable in the database,
So that i can monitor the data
Pls guide me regarding this.
Thank you
but how can one single database object point to multiple paths? Is the promissed solution to this in some other tutorial? I need to have 12 listeners😭
Hi Joed! I watched all your videoes about IoT Esp32. I am currently developing a website based project. I am concern about the API keys showing in the client side. How can I protect or hide it?
hi thanks alot u really helped me but can u share the code for android studio in the description ?
Hi, I found in tool/firebase/realtime databse /" get started with realtime database java" but not "get started with realtime database kotlin" is there a solution
Thank you for video sir. It was helpful in integrating esp32 with firebase. Can u help me out in coding part in Android studio? Can I get the access for Android studio code??
pls send me an email and I'll give you the code. thanks!
Que rei mano
Sir , can you pls provide code for the app?
This programe not working in my project. all the time serial.print send request failed
Please do one that shows the battery percentage
Pleaseeee🙏🏾
make more projects like this sir
I'll be releasing my new training series very soon. Thanks
i downloaded the "BLE scanner" on my android phone and it shows so many "mac addresses" and someone said it is people who took the jab. i went to walgreens since they give the jab there and i got over 200 "BLE mac addresses" when no one was in the store by the pharmacy. is it true it is the people who took the jab?
"private lateinit var binding: ActivityMainBinding "this line is giving me trouble what did you do to fix it because you skipped on the video?
Make sure to properly import the auto-generated class of this ActivityMainBinding. I have a separate video lesson that explains View Binding in Android. th-cam.com/video/pPl2dq3vLfg/w-d-xo.html
Thanks alot Mr. Joed for your excellent content.
Can you tell me how can I solve the challenge?
I have also sent you an email to get access for the code.
I repeat my thanks.
Let me check. Thanks!
@@joedgoh Thank you for your concern.
Wow nice and cool, i will like go get a copy of your codes sir(FILES) so i can edit and see round it please
The awesome video!! Can I access the source code?
Pls email me. joedgoh@gmail.com. thanks
Do you have a java version of this?
Hi, sorry, I don't have. Thanks!
how many stream can we have?
Probably only three, then I get the error "read error, not connected. " I can't find where to change it. Do you have this problem too?
In this library is funcion beginMultiPathStream but I'm testing it now.
@@piotrpiechowski6472 have u found the solution to get more stream?
Hey sir can you share the code with me?
Sent. Thanks!
Hello friend, can you share the source codes with me, please? Thank you.
Pls email me. Thanks!
can you provide source code
Yes, pls email me.
