Hey, i am beginner and i am working on my first "real" project. Therefore i need an 3x3 RGB LED. I am aware of the fact, that the Arduino hasn't got enough pins to control them all, but i heard something about a technique called Charlieplexing which makes this possible. Like i said i am a beginner and i hope that someone of you can help me out with it. Maybe someone of you did something similar before ? It would be super nice if someone could post me a Fritzing Graphic which shows me how to wire my LED's.
Thanks so much
