Seeeduino Xiao for RFID access control (RC522 reader)

Community General Info - Guidance
#1

Hi guys,

My first post here :grinning: (I searched but couldn’t find a lot on “access control” or “RFID cards”) and only on the blog below I found some info about access control but is for the Seeeduino V4.2:

So, I will like to port (reuse using the Arduino IDE application) the code I have on my Arduino Uno to the Xiao (because of the size) which is for an access control that can retain up to 5 RFID cards but I will like some feedback if this is feasible or not

Base on the picture below the Xiao have the pins that can connect to an RFID -RC522 reader

So all I need will be a digital pin to send the signal to a relay that can open the solenoid lock

Thank in advance for any support and help with this question

Best regards,

Hi, did you manage to get the Rc522 working with the Xiao? I am trying but not getting any result.
