Lumina

A Bluetooth Low Energy connected lamp

Lumina
The colors are mostly okay but we want lamps to be s-m-a-r-t-e-r. Like use the processing power of a smartphone to light in rhythm with music, simulate sunset when you go to sleep or turn on automatically when you walk into the room. Lumina does all that — on BLE and from your Android smartphone or tablet.

Components
Download the BOM list
The BOM (Bill of Materials) is the technically exhaustive listing of parts and other hardware items used to produce the working and tested prototype of any Elektor Labs project. The BOM file contains deeper information than the Component List published for the same project in Elektor Magazine. If required the BOM gets updated directly by our lab engineers. As a reader, you can download the list here.
