This is a working version of a remote control flashlight using Google Firebase. This allows control of your Android device flashlight through a native app and a web client. My demo is available here: 'https://flashlight-193812.firebaseapp.com', but unusable unless I turn on the remote control access on the app installed on my device, so download and build yours to test.
Also includes code for controlling LED using Firebase on an Arduino w/ ESP8266 Wi-Fi chip.
Further details will be provided soon.
