Control your RGB lights using Wifi RGB. Set the colour you want or let your lights change colour automatically using pre-defined programs.
Wifi RGB requires Arduino Uno/Mega and ethernet shield + specific Arduino code to work. Setting up the system is very simple and instructions are given in the beginning of the Arduino code. Detailed instructions can be found from the following url:
