Serial Comunication with Arduino

[s.monti.74]

no code runs on the pi to get the value, the value is read from arduino from the tag and arduino sends the value to the pi via serial. i don’t know which module of magic mirror I have to use to read that value and use it as a notification to switch the profile with MMM-ProfileSwitcher

ok, got it… you don’t KNOW if you got it in the pi yet…

this module should work for you

@s-monti-74

I think the module will read the serial port , and map that to some notification for other modules

devices: {
        '/dev/ttyACM0': {
          messages: {
            'Gesture: UP': [    < ---- message it reads from serial port (in your case rfid tag value)
