Home Automation Using Google Assistant

This includes creating Adafruit account then linking to IFTTT website then adding to Google Assistant for voice commands.

Story

The idea behind this is to control home devices with voice. On the market there are many devices available to do that. But making your own is awesome. So, let's do it. Build your personal assistant that will do the work for you. Just your assistant requires voice commands.
