#Firebase Room
2+
3+
##Software setup
4+
5+
1. Install[Arduino 1.6.9](https://www.arduino.cc/en/Main/Software)
6+
1. Install[Arduino ESP8266 core](https://github.com/esp8266/Arduino#installing-with-boards-manager)
7+
1. Download[FirebaseArduino library](https://github.com/googlesamples/firebase-arduino/archive/master.zip)
8+
1. Start Arduino
9+
1. Click`Sketch > Include Library > Add .ZIP Library...`
10+
1. Choose`firebase-arduino-master.zip` downloaded in step`3.`
11+
12+
##Hardware setup
13+
14+
1. Get a[Wio Link](http://www.seeedstudio.com/wiki/Wio_Link)
15+
1. Connect:
16+
- a[Grove - Vibration Motor](http://www.seeedstudio.com/wiki/Grove_-_Vibration_Motor) on`pin 5`
17+
- a[Grove - Light Sensor](http://www.seeedstudio.com/wiki/Grove_-_Light_Sensor) on`pin A0`
18+
- a[Grove - Red LED](http://www.seeedstudio.com/wiki/Grove_-_Red_LED) on`pin 12`
19+
- a[Grove - Button](http://www.seeedstudio.com/wiki/Grove_-_Button) on`pin 14`
20+
- a[Grove - Mini Fan](http://www.seeedstudio.com/wiki/Grove_-_Mini_Fan) on`pin 13`
21+
22+
##Configuration
23+
24+
1. Go tohttps://www.firebase.com/ and create a new Firebase
25+
1. Copy the`Firebase Hostname`
26+
1. Go to`Secrets`
27+
1. Click`Firebase Secrets > Shows`
28+
1. Copy the`Firebase Secret`
29+
1. Start Arduino
30+
1. Click`File > Examples > firebase-arduino > FirebaseRoom_ESP8266`
31+
1. Replace`example.firebaseio.com` with the`Firebase Hostname` from step`2.`
32+
1. Replace`secret_or_token` with`Firebase Secret` from step`5.`
33+
1. Click`Sketch > Upload`
34+
35+
##Play
36+
37+
1. Go to the Firebase console`Data` section
38+
1. Set`redlight` to`1` then`0`
39+
1. Watch the Red LED turn on and off in the room
40+
1. Same for`cooldown` and`brrr`
41+
1. Press the push button in the room
42+
1. Watch the`pushbutton` value change in the Firebase console
43+
1. Put your hand on the light sensor
44+
1. Watch the`sunlight` value change in the Firebase console
45+
46+
##Homeworks
47+
48+
- Build a[Firebase web app](https://www.firebase.com/docs/web/) that interacts with the room.
49+
- Connect other Grove modules to the room and submit new[PRs](https://github.com/googlesamples/firebase-arduino/pulls)
50+
- Reduce the number of Firebase API calls using`FirebaseObject` or`FirebaseStream`.
51+
- Watch or star the[GitHub repo repo](https://github.com/googlesamples/firebase-arduino)
52+
- Give[feedback](gitter.im/googlesamples/firebase-arduino)
53+
- Report[bugs](https://github.com/googlesamples/firebase-arduino/issues/new)
54+
-[Fork](https://github.com/googlesamples/firebase-arduino#fork-destination-box) and[contribute](https://github.com/googlesamples/firebase-arduino/blob/master/CONTRIBUTING.md)
