I’ve tried to connect everything, but my powerbank automatically shutdown after 1 minute of inactivity.
My other problem is that RFID reader doesn’t work properly: a fixed red led is switched on, but putting an empty card on it have no effect. Because I’m building 2 TonUINOs (and I have double components), I tried to use a second RFID reader, tried to change the 8 jumper cables, tried to use my second „AZDelivery TonUINO Set“, tried to use my second soldered PCB circuit but nothing changes.

Firmware Version: 0x0 = (unknown)
WARNING: Communication failure, is the MFRC522 properly connected?
Yes this is correct for that firmware. You can use any free pin by the way. So you don’t need to switch the LED pin. The issue is most likely that your nano does not output correct 3.3V. You’ll find similar issues on the forums.
Thank you molino: I saw that topic and I was planning to remove that resistor to solve the issue related to auto shutdown after a period of inactivity. Do you think that this could solve also the SD card reading problem?
An alternative would be to configure a wakeup by interrupt on the play button in the CheckStandbyTimer function just before deep sleep execution.
At the moment all interrupts are disabled before deep sleep. So there is no come back.
You may keep an Interrupt enabled on the play button and then call the setup() after sleep(). So tonuino will make a complete restart after wakeup.
A problem on DFPlayer Mini received with TonUINO kit from AZdelivery: SD card isn’t stable inside the slot, and you can remove it without pushing it until the click. This was a bigger problem for me, because I’m using an SD card extension cable, so when I assembled the box, moving all the pieces, the cable lost the contact with the slot. Same problem with another player from AZdelivery: I solve this adding a piece of scotch tape between the slot and the extension cable.
One of my 22 rfid cards won’t works: it could be damaged?
Hi, after some weeks my child love to use TonUINO!
After watching him usng it, I’ve some questions:
He place the card on the box the first time, so music starts, but after that, he usually move it several times, so the song stops and restarts from the beginning. It could be a good idea to implements a setting that disable this behavior if current song is the same of the placed card.
My child has 16 months and for now he has no idea of the meaning of the buttons on the box, so he usually play/pause or increase/decrease volume inadvertently. It could be a good idea to implements a keys sequence (like the one to enter in admin menu) to lock/unlock the buttons.
I’ve noticed that, sometimes, if I switch on the box and I place on it a „party“ card, it won’t play (also if I remove and place it again). The only way I’ve found is to place another card (that works fine), remove it and place the first card again.
you can make a modifier card for this. You have three options, wich can fit your problem:
„Krabbler-Modus“(Toddler Mode) it blocks the buttons, but not the cards
„TonUINO-Sperre“ (Lock Mode) it blocks all inputs
„KITA-Modus“ (Kindergarden Mode) it queues tha cards placed on the TonUINO. All inputs are working
The Modifier are activated by placing the modifier card on the TonUINO, then you hear a jingle.
The Modifier is active as long as the TonUINO is powerd. To Deaktivated you place the card again on the TonUINO.
