I'd like to drive 4 RGB LEDs from an Arduino Pro-Mini (5V version) using the PWM output pins. The LEDs would all be wired together, I don't need to control them individually. The LEDs are common anode drawing 20mA/color, like this one:

Digikey I was overwhelmed with the choices and didn't know where to start. Driver can be through-hole or SMD as long as the SMD can be hand soldered. I'd appreciate any suggestions.
