DeviceHive Android Things Demo demostrates the usage of DeviceHive Java Library with Android Things Project.
This project was created to control the WS2812B LED strip mode and communicate with IoT service. It can generate random color pattern or generate a color pattern that depends on audio record that was captured by the phone's mic.
This project includes two modules: mobile and things.
To make this module work you just should specify next properties in CommandService.java:
public static final String URL = "";
public static final String REFRESH_TOKEN = "";
public static final String DEVICE_ID = "";Then this module can be installed on you board that supports Android Things.
The things module was built on Raspberry Pi 3 to control the WS2812B LED strip via SPI Protocol.
The app is listening for commands from WebSocket connection established with DeviceHive server.
The mobile module sends commands to Raspberry Pi via DeviceHive server.
You don't need to specify any properties inside this module. You just need to install it on your mobile device. On the login screen you'd need to enter your credentials and the server url.
The mobile application can send several types of commands:
- BLINK
- RANDOM
- AUDIO
- OFF
BLINK command just turns on leds one by one. The leds are "running" outside from the center of LED Strip and back.
RANDOM command generates random HSV colors to emulate a ChristmasLight effect.
AUDIO command generates colors based on Audio signal that was recorded on Mobile Device and transformed with Fast Fourier Transformation algorithm (FFT).
OFF command just turns off the LED Strip.
