Blinks an LED on an arduino when a value changes in a firebase database.
Prerequisites:
- Node
- An Arduino or similar Johnny-Five compatible board
git clone
npm install
Plug your LED into your board as shown below. The default pin is 13.
Then connect via USB and enter npm start in the console. The LED will blink off and on for four seconds when the watched database path's value changes.
Use your own firebase project url and authentication. You can use any subdomain of firebaseio-demo.com without authenticating or creating a project, but note that the data could be changed or removed at any time.
Change watchedPath to the path in your database you want to watch. Use null to watch the entire database.
If you use a pin other than 13 for the LED, change it to match.
