Newb: can someone confirm my button circuit?

I have personally created a couple of little projects that use this topology

Gnd---Switch---Pin8

and then

pinMode(8, INPUT);
digitalWrite(8, HIGH);

to employ the internal pullup. It seems to work, but I have some lingering doubts about whether I am slowly burning up my Arduino pins. If any HW guys would care to comment...?

I may have to pay a visit to the automotive store. I read in another thread about a guy making a fountain sculpture thingy out of windshield wiper spray pumps. :slight_smile:

Thanks!
