how can i send someone the option to control my proj without the ability to change it?
You’ll need to provide some information about which version of Blynk you are using, and if it’s the new Blynk IoT then which type of subscription you have.
Pete.
for now im using the old blynk app, im having problem with the new one.
and the version is 0.61 like someone in this forum advise me.
Also i want to build a device that can send voice messages (live and recorded ones) and send music.
which electronic part will work with blynk?
thank you very much for the quick answers.
It’s in the Legacy documentation
Blynk doesn’t have that facility. It does have a very simple set of controls that can be used to send commands to your hardware device…
but the hardware would need to use those received commands to control some music player device that is capable of responding to commands from your board.
I’m not really sure what you are asking here.
Pete.
Where is the legacy documentation??
I try to make my question clearer, im trying to build a device the play a specific tune in a schedule timeing.
Is it posibale to do it in blynk?
And which kind of electrical diveces i need to make that happened.
Lets say, in this project there will be a live camera feed, the electrical part for this is esp32 cam.
What parts i need for sending audio brodcast or only recorded ones?
I’ve just given you two links to it in my previous post!
Blynk can be used to trigger an action at a specific time, and that action could be used by your hardware to “play a tune” via a speaker or other device attached to your hardware.
That tune would NOT play on your mobile device (phone) though.
To achieve that you would need to trigger a notification and the ability to play a tune would depend on your phone’s OS amongst other things.
It really depends on what EXACTLY you are trying to achieve. If you want to play a small melody via a speaker attached to your device then a speaker is probably all you need.
If you want to trigger n MP3 to play then you’d need an MP3 player that’s capable of being controlled by an MCU. But neither of these solutions are anything to do with Blynk. Blynk is simply the tool to trigger that action either via a timer ot another type of widget.
If you need more info on playing tunes via an MCU then there are more appropriate forums to gain that sort of information.
The video stream widget has the ability to play a a video stream, with embedded audio, on your mobile device. If you want to enable that to work outside of your home network then you’ll need to make the URL of the video stream publicly visible, probably with a DDNS service, DDNS updater and port-forwarding.
Pete.
Thank you very much Pete. Im really new to all this technology so sory for the ignorant.
I try to send live video of my dog to my phone with esp32 cam, and also send him voice messeges and play music 
.
With the video im good more or less. Now i need to learn how to send voice messeges and play music/tune…
You sey that i need a mp3 controlled by MCU, and a scheduler that controll the play button?
Like this one?
Messages that you speak into the phone, or pre-recorded messages?
Pete.
Both. When my dog is eating than a recorded message will sound. And if i wont to send him something when im at work or something than live ones. I orded that mp3 i send in the previous message, i hope it wasn’t a mistake
Personally, I’d by a PetCam, an Alexa and a Spotify subscription.
That way you can have a two-way conversation with him via the PetCam, and use Alexa to play whatever sort of music he says he wants to hear at the time.
Pete.
Im making a college project for a smart housing system for dogs. And it needs to be cheep and practical.
Im using Blynk for controlling threw the wifi.
When the dog is eating i want to play a music for him and also send him voice messege. I think alexa and petcam colud be expensive and a little bit cheating because i need to make everything by myself you see.
So esp32cam will be my video device and i purchase that mp3 player:

Now i need to figure it out how to control them both with the Blynk app…
