as my digital pins are nearly all in use, I asked myself if there is a possibility to connect a pushbutton like this one (http://www.conrad.co...product/706140/) [font="arial, helvetica, sans-serif;"]to the Analog pins?[/font]
Is this possible via the analog pins and if yes, is there some kind of tutorial how to do it with the analog pins?
Is there some restriction in the cable length between button and pin? Do I need additional resistors or something like that? (sorry I'm no electronics guy ;-))
Thanks in advance.
