NFC -> Audio file

Other Hardware Audio
1

Hello everyone, I am Pier and I joined the forum because, along with my nephew who is studying electronics, we plan to make a project based on Arduino but we need help with programming the functions and events of the shields.

This is our project:

On Arduino (1) we are going to mount a shield that allows to record/play audio files based on certain events, and a second shield that mounts an NFC sensor, which allows to send to the Arduino tag data; our goal is to read a tag and play an audio file stored in SD, but if the tag has never been read before, It has to start the recording of a new audio file to associate with the tag; in short, a kind of voice recorder with nfc.

we found these shields:

FE-8190-AUDIO_SHIELD

SE-SLD01097P

Our problem is:
From what we seem to read in the specifications is not possible to control the recording from an event that is not the push of a button, it is necessary that the tag has already been programmed and entered into the software and that the audio file is already present, but clearly would not have a dictaphone but only an mp3 player !!!

Anyone can help?

thank you guys

I don't know the shields you posted and I don't know which specifications you are talking about, but from what I know about how NFC works, you CAN read any tag from an NFC chip. It doesn't have to be stored already. And it is certainly possible to trigger an event from a read NFC tag and not only from the push of a button. Also it is possible to read and write audio files.
So I don't see why your project should not be possible.
I would just consider using at least an arduino due because it has much more processing power and built in analog read/write which makes it easier working with (lo-fi) audio files.
Of course if you use a shield the audio will not be lo-fi but even then I would consider using the Due because... it's better. :slight_smile:

I don't know if there are audio shields for the due out there but I have built one so if you need an audio shield and can't find one, I'd be happy to help you!
