I'm working on a shield for the arduino and would like to put a DIP switch on the board. I found and built this tutorial; http://www.arduino.cc/en/Tutorial/ShiftIn
But I was wondering. Is it possible to have the dipswitch without all the resistors. Is the cd4021b not capable of doing his own pulling up or pulling down(like arduino). I googled a lot on the dip switch, and mostly they're connected without a resistor on every single pin.
Anyone has an idea, or tutorial how to do it? Your help is, as always, much appreciated.
