What you need to realize it without
a high power
- (1) Arduino UNO
- (1) ElectricIMP "SD"-card and a IMPShield or IMP- Breakout board (Sparkfun product page)
- (1) breadboard for prototyping
- (1) RGB- LED
- (1/ optional) Philips Hue starter package
You also need a local webserver. For example a Raspberry Pi with Lighttpd- web server with php- support. You'll find more information here or with help of google: http://www.raspberrypi-spy.co.uk/2013/06/how-to-setup-a-web-server-on-your-raspberry-pi/
You need the local webserver because Philips Hue isn't very secure
to let it operate in the internet with portforwarding, there is no authentication mechanism.
As mentioned before, the focus lies on the software side, but in the next step you'll find a short description of the high power led circuit I've built...
