MMM sensor+WS2812b and MM CONFIG RESET button

  • This app was made to add some kind functionality to Magicmirrors run on RPis.

    App allows you to:

    • control LED strip by sensor and also
    • rreset MagicMirror’s config.js file with a hardware button connected to Raspberry (so config should be set to default values). The operation will be confirmed by three red light blinks.

  • Hello, I am very interested in your project, I would like to know if it is possible to have more details, I am a beginner 😁.
    Is it possible to know the connection?
    Is the switch just a push button or a stop market button?
    thank you so much
    I love what you did.
