The MATRIX Creator is a hat for the Raspberry Pi that has been described as a Swiss army knife for your Pi.  It boasts a suite of communication protocols, a ring of RGB LED, a microphone array, and more!


In this webinar we Samreen and Afred will focus on using your NFC to preserve privacy w/ cloud based voice AI on your IoT Device.



You will learn how to utilize Google’s Voice AI libraries with a “push-to-talk” model to voice-control your hardware project. Program NFC tags to activate your MATRIX Creator’s microphones, thus preventing the transmission of irrelevant data to the cloud, while also authenticating the user.


What attendees will learn:

  • How to program NFC actions in JavaScript on the MATRIX Creator
  • How to implement NFC-activated microphones on the MATRIX Creator
  • Examples of how users can develop their own security measures for connected assistants
