Sorry I have so many questions...I'm gonna have a lot more. this is the lcd screen I'm looking at:

Could run a naked ATmega168A and use the internal clock at 8Mhz to communicate with the screen? I could run the whole board at 3Volts. I understand there may be baudrate limitations but I'm talking about pretty limited amount of data. (max or 32 characters) If I understand it correctly I could treat that as a lilly pad for programming purposes. Other than the lcd all i'm doing is taking 2 switch inputs and controlling and opening and closing some transistors.
