forgotten, if you use a serial LCD like I did, then you only need to use 1 digital pin for it, that frees up some digital pins. If you already have an LCD, sparkfun sells a serial backpack for LCDs, i'm not sure which ones it will fit though. You can probably put the buzzer on an analog pin, I set mine to trip a relay, then connected the buzzer directly to my 12v power supply.
