Hello everybody!!
I’m getting quite crazy here! I’m planing on building a tonuino for my daughter as a christmas present. I managed to gather everything I need. For the moment I’m just trying to make things work without assembling the case and without the batteries. So I have a classic plate, the kit from azdelivery (rfid reader, dfplayer, and arduino).
I have put together everything as indicated. I am powering the system from the 5v pin just next to the dfplayer.
I have an sd card formated in fat32 with the structure as said everywhere: both folders advert and mp3, music in 01, 02 folders, and files as 001.mp3, etc.
I have tried separately both arduino and dfplayer and they both work. dfplayer reproduced music by itself with the card I’m using for the tonuino and simple speakers, with an independent setup.
I have loaded the 2.1 version of tonuino, enabled pololu and also 5 buttons in the arduino application, as I will be using 5 buttons on my configuration. I’m not using pololu yet, as i’m just testing the system.
when everything is put together, I get light on the arduino, a red LED on the RFID card reader, and a red LED on the dfplayer, but nothing else happens. No sound, I click buttons and nothing, Put a card on the reader and no reaction, just a soft continuous beep from the speaker (or a buzz more like)… well, I’m really lost here.
I conected the 5 volts soldered directly to the tonuino classic, to make sure is not poor cable gauge.
I attach some photos (only one as I am new to the forum), but any help would be really appreciated. Thanks,
David
