Paul, thank you for the response. Yes, that is the shield that I currently have hooked up, and everything that I have read indicates that it makes inefficient use of the pins. However, I have it, it's here, and I'd like to make the most of it.
Again, excuse my ignorance, but if I use analog control of the RGB LED(s), does that relieve me of the need to use PWM? Is it one or the other (either analog control OR digital control)?? That was my understanding from reading the numerous digital-vs.-analog discussions. From reading the pinout of the LCD shield, it doesn't utilize any of the analog pins. Is there a way to accomplish the RGB control using exclusively analog control WHILE still using the keypad shield???
That is my ultimate goal!
