Answer 1:
CrossRoads:
internal pullups:Serial.begin(9600);
pinMode(53, INPUT);// assumes switch closure connects pin to Gnd
digitalWrite (53, HIGH);
// IDE 1.0.1 also supports:
pinMode(53, INPUT_PULLUP); // seperate digitalWrite not needed
EXACTLY! that is what I needed!!! I needed the digitalWrite part! The INPUT_PULLUP does not work on pins 22-53 on the Arduino Mega.
My aim is to make a miniature keyboard. (I will need 38 buttons for that 
)
Where can I get A LOT of cheap miniature buttons?
