Hello, my name is Jean Paul Delaye, I have done an iPhone App called Cromalight.
Cromalight is an iPhone® App, that allows you to take control of switching up to 6 lights or home applinces, it also has an ambient color picker interface and 4 chromotherapy presets.
"Cromalight was designed with the aim of helping a disabled child. The basic idea was to provide a remote control of light switches, bells or appliances. The design process led us to discover ARDUINO and their cheap and easy-installation components, as well as the easy way to control a RGB LED strip. We noticed that it could not only be used to put colored light in the environment, but also as a method of communication.
I really appreciate your comments
