Hey Google, Turn on the light - DevFestRajkot19

Android Things is an Android-based embedded operating system platform by Google. Android Things lets you build professional, mass-market products on a trusted platform, without previous knowledge of embedded system design. This talk covers how to start with Android Things, Flash OS on development board and Connect devices with NXP Pico i.MX7D platform and control that using Android mobile & Google Assistant application.

You will be learning below things,
- Getting started with Android Things
- How to build and flash OS on development board
- Control devices through Google Assistant (NXP Pico i.MX7D, Breadboard, LED, Google Home, Dialogflow application, Firebase Real time database & Cloud Functions)
