Serial Comunication with Arduino

[sdetweil]

How did u implement the pi side? Python?

@sdetweil
mmmmmm… I’m using some MMM modules installed on my mirror, hoping that there is a module like MMM-ArduPort that I can use for my purpose
:flushed_face:

[sdetweil]

@s-monti-74 wht do you want to do with the rfid tag value? besides display it? use it as a profile id?

[s.monti.74]

Yes I want’t su use the tags as a profile ID and manage modules with MMM-ProfileSwitcher.

so all the members of my family (each in possession of his tag), can have custom modules

thank you very much for your advices

@s-monti-74 said in Serial Comunication with Arduino:

MMM-ProfileSwitcher

so, you would lookup the profile name from the rfid tag, and send a messge for that profile

from the MMM-ProfileSwitcher readme

this.sendNotification('CURRENT_PROFILE', 'DESIRED_PROFILE_NAME_HERE');

[sdetweil]

@s-monti-74 so, once again, what code running on the pi gets the rfid value?

python script or ???

[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

[sdetweil]

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

this module should work for you

thanks a lot sdetweil

@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)
