Hi, finally my firsts TonUINOs are ready for Christmas!
It wasn’t easy for me to reach this goal, but I’m satisfied, and thanks to all who helped me on this forum.
My biggest difficulties have been:
- Zero knowledge on electronic circuits
- Zero knowledge on soldering
- The issue on Nano explained here
- 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?
