A Browser accesible interface UI to control The CoffeePlantBot Arduino smartgarden using Web Bluetooth:
WEB Bluetooth is a not a standard yet, it works well with Chrome/Chromium browser under Linux, Windows and Android.
Web Bluetooth works under BLE 4.0 Low energy devices, the one used on this testing was a cheap chinese version of it. Firmware unknow, board is HM-10, supposedly. You only have to find the Service UUID and the Characteristic UUID and make it work.
