If you don't do that you should set the pin to output a low for several instructions, then set it back to input and read the read the pin immediately, so it doesn't have time to drift back toward a high level. You may not read high properly then though. Connecting a capacitor from the pin to ground would make it float around more slowly. But if you use an external component it should be a pull-down resistor. ___________________________________________________________________ Get the Internet just the way you want it.
