For the experienced Arduino user this total view makes immediate sense. However, if you're a beginner just like me, a breakdown in steps can be useful.

Drawings were made with software by "Fritzing" (http://fritzing.org).

I have used a RGB Led with a common Anode (3 Cathodes: R, G, B). Therefore the setup may seem a bit ackward. The consequence is that in the sketch (step 3): HIGH=off and LOW=on.
