To set the mood: RGB LED :: mbeckler.org And I've got an Arduino Diecimila. First, in the circuit schematics section, the author explains that the common anode is connected to an external +12v power supply, and that the cathodes are connected individually to pins 9-11. From what I've been reading,…
