A sample project that creates a "Home Lighting System" using Android Things and Firebase integration to control turning three LEDs on/off. To use, a Firebase instance must be created and two apps adds for the Android Things app and the companion phone app and add the google-services.json files to their respective modules in the project. The related blog post can be found here. JSON structure for the Firebase database is as follows:
{
"lighting_system" : {
"blue_on" : false,
"green_on" : false,
"red_on" : false
}
}
Expected wiring of the Raspberry Pi and LEDs is below -- if you choose to use a different device or different GPIO pins, be sure to update the pin values in the MainActivity for the Android Things app.
