Eleven days to go until Christmas Eve and the Christmas elves from AZ-Delivery.de are becoming more and more generous in their choice of gifts. Especially the Christmas elf has a surprise for day 13 for young and old who do not want to do without audio books or music. Sure, you can fall back on a commercial product especially for your dear little ones, but with little hardware, some code and a bit of tinkering mood you can put a smile on every child's face with the TonUINO Set.
What's behind the door today?
- Nano V3.0 with Atmega328 CH340 100% compatible with Arduino Nano V3
- AZDelivery Mini Mp3 Player
- RFID Kit RC522 with 10 RFID boxes and one RFID chip
Illustration 1 shows once again all the components that you will find in the TonUINO set.

What else will you need
- Micro SD card with a maximum of 32GB
- Some odds and ends (cables, 1kOhm resistor, buttons)
- A passive bookshelf speaker
- USB 2.0 A male to mini B male
- Arduino IDE in the latest version
- The libraries MFRC522, DFPlayer Mini Mp3 by Makuna and JC_Button with all the dependencies how to do this, we show here.
Alternatively, you can also purchase a prefabricated circuit board from the developer of the TonUINO, follow the link to https://www.voss.earth/tonuino.
Since the set does not include the mentioned circuit board, Figure 2 serves as a wiring aid for you. The type of push button and also the loudspeaker is up to you, but make sure that it does not have too high a power (recommended 3 watts).

When you are finished, the code still has to be transferred to the Nano V3.0. To do this, clone that Git repository from the developer and after unzipping open the file
Tonuino.ino and then load everything onto the micro controller.
Figure 3 shows a fully wired TonUINO on a breadboard.

The developer of TonUINO is now working in a community on the project and so improvements are constantly being made in the Git repository linked above. Just look on the page https://www.voss.earth/tonuino over from time to time.
By the way, you can also carry out other small projects with just a few additional components:
