    Hello, I am interested in displaying Serial communication between arduino and Magick Mirror.

    Something similar is used by MMM-Gesture but I have not been able to modify the code , I would like to display the numerical information from my arduino projects via USB serial.

    Does anyone use something like that?

    Thank you for advice.

      MMM-Gestur

      Hi I have a similar need
      I wan’t to send notifications to Magic Mirror (to switch the profile) using an RFID sensor connected to an Arduino
      If I pass my personal tag near the RFID sensor connected to the Arduino, I want to switch the profile of magic Mirror
      Does anyone know if is possible to use the serial comunication in this way from arduino and RPi ?

        sure… serial is serial…

        arduino - write

        https://www.arduino.cc/en/serial/write
        

        pi - read (using on.data event)
        in node_helper.js

        https://github.com/nebrius/raspi-serial
        

        then the ‘on data’ event can signal the module if needed,
        with sendsocketnotification()

          so I abandon the idea of ​​using the arduino outputs (reduced to 3.3 volts) in the GPi input of the RPi and the mmm-buttons module?
          thank you very much

              HI sdetweil, thanks
              I have connected my Arduino to RPi with USB cable and I read (on Arduino values of RFID tags) on the Serial monitor of Arduino IDE installed on my RPI
              Now I don’t understand which MMM Magic Mirror module I have to use to manage serial datas that I receive from Arduino

              thanks a lot
              bye

                @s-monti-74 I think u will have to create your own module

                    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

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