FirebaseDemo

FirebaseDemo is a sample that shows basic usage of the FirebaseArduino API.

Software setup

1. Install Arduino 1.6.9
2. Install Arduino ESP8266 core
3. Download FirebaseArduino library
4. Start Arduino
5. Click Sketch > Include Library > Add .ZIP Library...
6. Choose firebase-arduino-master.zip downloaded in step 3.

Configuration

1. Start Arduino
2. Open File > Examples > FirebaseArduino > FirebaseRoom_ESP8266
3. In FirebaseRoom_ESP8266: Replace WIFI_SSID and WIFI_PASSWORD with WiFi credentials
4. Go to https://firebase.google.com/console/ and create a new Firebase Project
5. Go to Database
6. Copy the Database hostname (Database URL without https:// and trailing /)
7. In FirebaseRoom_ESP8266: replace FIREBASE_HOST with the Database Hostname
8. Go to ⚙ > Project Settings > Database > Database secrets
9. Click Firebase Secrets > Show
10. Copy the Database Secret
11. In FirebaseRoom_ESP8266: Replace FIREBASE_AUTH with Database Secret
12. Select the board Board > ESP8266 Modules > NodeMCU 1.0
13. Select the serial port Port > /dev/tty...
14. Select the upload speed Upload Speed > 115200
15. Click Sketch > Upload

Play

1. Go to the Firebase console Data section
2. Watch the data being modified as the sketch runs
