Hello guys,
I've created with a friend a project using Arduino and Android to control the light color of a lamp.
You can see photos, a video and a podcast (video and podcast only in Portuguese, sorry) at his blog:
The video auto-explain the usage of the system, so you can understand even it is in Portuguese. See the video direct on Viemo.
The code and schematics are in the project luminaria-rgb on my GitHub account.
Future versions will include Bluetooth (this one uses Ethernet with ENC28J60 controller - I'm using my modified Ethernet library for this work).
Please let me know what do you think about the project.
