@s-monti-74 So do you use an Arduino Uno or not??
Why do you download the Arduino IDE on the Rpi?? Is it just for programming the UNO (i use the IDE on my Windows machine) or to read the serial commands??
How do you connect the RFID board RC522 to the Rpi or to the UNO?? … the board has 7 used pins and 1 unused, assuming we are talking about the RFID-RC522 board

@s-monti-74 Stefano One more question if you use the Arduino Uno how do you connected it to the Rpi??

[s.monti.74]

I have bought this on Amazon:
AZDelivery ⭐⭐⭐⭐⭐ Kit RFID RC522 13,56MHz con Reader, Chip e Scheda per Arduino e Raspberry Pi con eBook Gratuito!
7€

I have connected Arduino with PI via USb cable
with this connection I upload sketch to Aruino (this is why I use Arduino IDE on PI) and with the same connection datas (RFID tags) are tranfered from Arduino to PI (and the module of magic Mirror does the rest of the job)

@s-monti-74
Is the Arduino code you copied on the above post the complete one?? It makes no sense to me …also what wiring scheme are you using for the RFID board to the Uno??

Always thank you for the response

Another thing can you please check for errors the MMM-Serial-Notifications module entry code on the config… that you posted on the above post… it mentions an S and A instead of G and no TAG1 or TAG2

As always
Thank you again
Denis

@richland007 the uno is connected to the pi serial port from the uno serial port.

So the uno code writes to it’s port, and the data causes an serial event on the pi with the data.

@sdetweil Yes Sam but is the UNO to Rpi connection using Dupont wires and the TX RX pinouts or through the usb connection which is also used to upload the sketch to the UNO… i thought it was through the usb??

[sdetweil]

@richland007 i believe he uses both… usb for sketch and serial for data

@richland007 I have modified the code before update it, to make it simpler and probably something is wrong.
I use 2 tags, the first to recognize me (S) and the second to recognize my wife (G)
for serial communication, later I send you a photo

@s-monti-74 Great i got the schematics now :)

Can you please post again the complete Arduino code

Thank you very very much
